  • Isomerism and its classification.
  • General Organic Chemistry (GOC) concepts including reaction mechanisms, electronic effects, and attacking reagents.

The course aims to build a solid foundation, enabling students to tackle the organic chemistry portion of the 12th-grade syllabus with confidence.

Introduction

The instructor, Shura Grover, welcomes students to the NCERT Wallah platform, emphasizing that the session will cover essential organic chemistry concepts for class 12th. The bridge course is designed for students who need to strengthen their understanding of organic chemistry, especially those who found it challenging in 11th grade. The course will cover basics necessary for class 12th, addressing common myths about skipping 11th-grade organic chemistry.

Success Through Effort

The instructor encourages students to dedicate themselves to studying with determination. Success may not come with every attempt, but every success is rooted in effort.

Organic Chemistry Basics

The session will cover the basics of organic chemistry, starting with carbon and its related concepts. This includes understanding the types of bonds carbon can form, hybridization, and IUPAC nomenclature. The content will also relate to class 12th chapters such as Haloalkanes and Haloarenes, Alcohols, Phenols, and Ethers, Aldehydes, Ketones, Carboxylic Acids, and Amines.

Rules for the Session

To make the most of the session, students are advised to use a single notebook to keep their notes organized. They should also have three colored pens (blue, black, and pencil) to build and revise structures effectively. Active participation is encouraged.

What is Organic Chemistry?

Organic chemistry is defined as the study of hydrocarbons and their derivatives. Hydrocarbons are compounds containing only hydrogen and carbon. Derivatives are compounds derived from hydrocarbons by replacing one or more hydrogen atoms with other atoms or groups. For example, CH3Cl is a derivative of CH4 (methane). Organic compounds must contain at least one carbon and hydrogen atom.

Representation of Organic Compounds

Organic compounds can be represented in four ways:

  1. Molecular Formula: Indicates the exact number of each type of atom in a molecule (e.g., C4H10).
  2. Condensed Structural Formula: Shows carbon-carbon bonds but omits carbon-hydrogen bonds (e.g., CH3-CH2-CH2-CH3).
  3. Expanded Structural Formula: Shows all bonds between all atoms (C-H and C-C).
  4. Bond Line Notation: Represents compounds using lines to indicate bonds, with carbon atoms at the corners and ends of lines, and hydrogen atoms are implied.

Practice Questions: Condensed Structural Formula

Students practice converting structures into condensed structural formulas. Examples include converting ethane (CH3-CH3) and propane (CH3-CH2-CH3) into their condensed forms.

More Practice: Complex Structures

More complex structures are presented, and students are guided to represent them in condensed form, reinforcing the concept with examples like branched and cyclic compounds.

Cyclic Compounds

The lesson covers cyclic compounds, explaining how to represent them in condensed form, such as cyclopropane (CH2-CH2-CH2).

Bonds and Hybridization

Two types of bonds are explained: sigma (σ) and pi (π) bonds. A single bond is always a sigma bond. A double bond consists of one sigma and one pi bond. A triple bond consists of one sigma and two pi bonds. Each bond contains two electrons. Hybridization is calculated by counting sigma bonds and lone pairs, excluding pi bonds.

Calculating Hybridization

The method to calculate hybridization is explained:

  • If the sum of sigma bonds and lone pairs is 4, the hybridization is sp3.
  • If the sum is 3, the hybridization is sp2.
  • If the sum is 2, the hybridization is sp.

Negative charges on carbon indicate the presence of a lone pair. Pi bonds are not considered for hybridization.

Sigma and Pi Bonds Practice

Students practice calculating the number of sigma and pi bonds in various structures, including single, double, and triple bonds.

Bond Line Notation and Hybridization

Students practice identifying sigma and pi bonds and determining the hybridization of carbon atoms in bond line notation structures.

Degree of Carbon

Carbon atoms are classified based on their degree:

  • Primary (1°): Bonded to one other carbon atom.
  • Secondary (2°): Bonded to two other carbon atoms.
  • Tertiary (3°): Bonded to three other carbon atoms.
  • Quaternary (4°): Bonded to four other carbon atoms.

Degree of Hydrogen

Hydrogen atoms are classified based on the degree of the carbon atom to which they are attached:

  • Primary (1°): Attached to a primary carbon atom.
  • Secondary (2°): Attached to a secondary carbon atom.
  • Tertiary (3°): Attached to a tertiary carbon atom.

Quaternary hydrogen atoms do not exist.

Degree of Alkyl Halides

Alkyl halides are classified based on the degree of the carbon atom to which the halogen is attached:

  • Primary (1°): Halogen attached to a primary carbon atom.
  • Secondary (2°): Halogen attached to a secondary carbon atom.
  • Tertiary (3°): Halogen attached to a tertiary carbon atom.

Degree of Alcohols

Alcohols are classified based on the degree of the carbon atom to which the hydroxyl (OH) group is attached:

  • Primary (1°): OH group attached to a primary carbon atom.
  • Secondary (2°): OH group attached to a secondary carbon atom.
  • Tertiary (3°): OH group attached to a tertiary carbon atom.

Degree of Amines

Amines are classified based on the number of alkyl groups attached to the nitrogen atom:

  • Primary (1°): One alkyl group attached to the nitrogen atom (RNH2).
  • Secondary (2°): Two alkyl groups attached to the nitrogen atom (R2NH).
  • Tertiary (3°): Three alkyl groups attached to the nitrogen atom (R3N).

IUPAC Nomenclature

Organic compounds have two types of names: common names and IUPAC names. IUPAC (International Union of Pure and Applied Chemistry) nomenclature provides a systematic way to name organic compounds.

Common System vs. IUPAC System

The common system names organic compounds based on their origin or properties. The IUPAC system follows a set of rules for naming compounds. Key prefixes include n- (straight chain), iso- (branching on the second carbon), and neo- (branching on both sides of the second carbon).

IUPAC Nomenclature Rules

The general format for IUPAC names is:

Secondary Prefix - Primary Prefix - Word Root - Primary Suffix - Secondary Suffix

  • Word Root: Indicates the number of carbon atoms in the main chain (e.g., meth- for 1 carbon, eth- for 2 carbons, prop- for 3 carbons, but- for 4 carbons).
  • Primary Suffix: Indicates the type of bond between carbon atoms (e.g., -ane for single bonds, -ene for double bonds, -yne for triple bonds).
  • Secondary Suffix: Indicates the functional group (e.g., -ol for alcohols, -al for aldehydes, -oic acid for carboxylic acids).
  • Primary Prefix: Indicates if the compound is cyclic (cyclo-).
  • Secondary Prefix: Indicates substituents or side chains (e.g., chloro-, bromo-, methyl-).

IUPAC Practice

Students practice naming compounds using IUPAC rules, including examples with substituents, double bonds, and cyclic structures.

Priority Order of Functional Groups

A priority order of functional groups is presented to determine which group takes precedence as the principal functional group (secondary suffix) when multiple functional groups are present. The order includes carboxylic acids, sulfonic acids, acid anhydrides, esters, acyl halides, amides, nitriles, aldehydes, ketones, alcohols, thiols, and amines.

IUPAC Naming with Multiple Functional Groups

The lesson explains how to name compounds with multiple functional groups, using the priority order to determine the principal functional group and naming the other groups as substituents.

Isomerism

Isomerism occurs when two or more compounds have the same molecular formula but different properties. These properties can be physical or chemical.

Types of Isomerism

Isomerism is classified into two main types:

  1. Structural Isomerism: Compounds have the same molecular formula but different structures.
  2. Stereo Isomerism: Compounds have the same molecular formula and structure but different arrangements of atoms in space.

Structural Isomerism Types

Structural isomerism includes:

  • Chain Isomerism: Different arrangement of the carbon chain.
  • Position Isomerism: Different positions of functional groups or multiple bonds.
  • Functional Isomerism: Different functional groups.
  • Ring-Chain Isomerism: Compounds can exist in both ring and chain forms.
  • Metamerism: Different alkyl groups around the same functional group.
  • Tautomerism: Isomers that differ in the position of a proton and a double bond, often seen in carbonyl compounds.

Chain Isomerism Explained

Chain isomers have the same molecular formula but differ in the arrangement of the carbon chain.

Positional Isomerism Explained

Positional isomers have the same molecular formula and carbon chain arrangement but differ in the position of functional groups or multiple bonds.

Functional Isomerism Explained

Functional isomers have the same molecular formula but different functional groups.

Ring Chain Isomerism Explained

Ring-chain isomers have the same molecular formula but can exist in both ring and chain forms.

Metamerism Explained

Metamers have the same molecular formula but different alkyl groups around the same functional group.

Tautomerism Explained

Tautomers are isomers that differ in the position of a proton and a double bond, often seen in carbonyl compounds.

Isomerism Practice Questions

Students practice identifying types of isomerism in given examples.

Stereo Isomerism Introduction

Stereo isomers have the same molecular formula and structure but different arrangements of atoms in space.

Chiral Centers

A chiral center (or chiral carbon) is an sp3 hybridized carbon atom bonded to four different groups. The presence of a chiral center does not guarantee optical activity.

Mirror Images and Superimposability

The concepts of superimposable and non-superimposable mirror images are introduced. Non-superimposable mirror images are chiral and can exhibit optical activity.

General Organic Chemistry (GOC) Introduction

The final section introduces General Organic Chemistry (GOC), which explains the flow of reactions and the electronic effects that influence them.

Reaction Mechanisms

A chemical reaction involves a substrate and an attacking reagent. The mixture of these two forms the reactant. Before forming the product, the reaction goes through a transition state or an intermediate stage.

Electronic Effects

Electronic effects, including inductive, resonance, mesomeric, hyperconjugation, and electromeric effects, are studied within the substrate. Attacking reagents are either electrophiles or nucleophiles. Intermediates include carbocations, carbanions, and carbon free radicals.

Bond Fission

Bond fission (breaking of bonds) occurs in two ways:

  1. Homolytic Cleavage: Each atom takes one electron, resulting in radicals.
  2. Heterolytic Cleavage: One atom takes both electrons, resulting in ions (carbocations and carbanions).

Inductive Effect

The inductive effect is a distance-dependent effect (valid up to four carbon atoms) caused by electronegativity differences. It can be either +I (electron-donating) or -I (electron-withdrawing).

Resonance Effect

Resonance involves the delocalization of pi electrons in conjugated systems. Resonating structures are created to explain properties that a single structure cannot.

Mesomeric Effect

The mesomeric effect is similar to the resonance effect but is unidirectional due to the presence of a specific group. It can be either +M (electron-donating) or -M (electron-withdrawing).

Electromeric Effect

The electromeric effect is a temporary effect that occurs in the presence of an attacking reagent on a multiple bond system.

Hyperconjugation

Hyperconjugation involves the delocalization of sigma electrons. It requires the presence of alpha hydrogen atoms (hydrogen atoms on the carbon atom adjacent to a double bond).

Electrophiles and Nucleophiles

  • Electrophiles: Electron-loving species (positive charge or electron-deficient).
  • Nucleophiles: Nucleus-loving species (negative charge or electron-rich).

The lesson explains how nucleophiles attack positive centers and electrophiles attack negative centers in chemical reactions.

Conclusion and Farewell

The instructor summarizes the topics covered and encourages students to practice and solve NCERT questions. The session concludes with motivational lines and a farewell.

0:57 no mam how to do organic string of 12th If yes, please tell me that too yes everyone can hear my voice clearly please Confirm me once in chat section Ma'am please get everything done with the basics Son, every single thing will be covered from the very basics This will be done which you will need for class 12th If necessary, I welcome you. I welcome you to NCERT channel Now I do bridge in bridge course You can understand the meaning of the course from the name itself There will be a bridge, that is, when you go from one path If you are going in another direction, then the way from which you are going that is your bridge which is your This method will save your time as well as

1:42 You have to cover some such important topics You will have to do that which is required in 12th Look, there aren't many like that yet Kids think that if we go straight to class 12th If we go and study, are we not clear? This is a myth, it will not be clear to anyone It has to be cleared, son, work hard on it He does it and clears such a thing also No, but yes, this is a bridge course basically This is for those students who are somewhere 11th has that much grip in its organic couldn't make it or can i say those This is for students who are interested in organic I feel a little scared now it's like this son when you If you go to class 12th then there will be many You will find the chapters if you look. The part two booklet of NCERT that is He completed Complete Organic Chemistry It's full of organic chemistry okay so a lot of kids get scared that

2:29 brother what happens in 11th at the end You get organic and by the time you reach the end Energy goes down and so does the preparation If it is not possible to do so then skip it Many children think that only two are enough There is a chapter, I will read it later some other time if you take it or even try to do it Maybe the papers would come, the exams would come basically they are board schools If you can't do it then there's no problem This is what I would say if you looked at 11th carbon I have not read the C of hydrogen also the H of hydrogen If you don't know then there is nothing to worry about In this we will cover the very basics Right everyone let's start today's session does not know organic at all how to do 12th how to do so and so

3:15 As many questions as there are queries You will be clear after today's session ok so before we start for all of you There is a lovely line, son, give this to your life I definitely want to implement it, I am looking forward to it will you go Success may not be achieved in every attempt You might not be successful in trying, but Every success is because of effort but The reason behind every success is effort We must extend our hands towards that effort okay we want to increase it and in today's session you will Everyone has to promise me, you all will do the same I will study with such dedication, with such dedication

4:00 I have come to teach you today right okay Let's start today's class so basically what we will do is this is back two basics okay those small little things There are topics, I will pick them up and keep understanding them Where will we start chemistry from? and how do we get it in 12th If we want to apply then this will be our goal Maam the 11th has passed as it should have happened brother I am in 12th class or so for boards am I preparing for neet am i preparing for jee I am preparing for NEET JEE or Should I say boards or CU in these exams How is chemistry asked in 11th class Also tell me how it will be useful in 12th okay so first of all you have to do this We have to understand what is the flow of this journey of ours

4:49 according to whom we will live everything If you are going to study then son should study organic what is chemistry in these two words i can say this here we First of all we will take care of the basics of organic There are so many things about carbon Now we will understand many things related to carbon All the concepts are for example if you If you take up the carbon topic then initially you will We will also understand when one carbon is connected to another carbon forms a bond with each other, then what is that bond Let's talk about how many types of bonds can be formed what hybridized All the terminology related to You will see after that I will tell you IU PSC Nomenclature what is clutch brother like you in comment i

5:35 I am looking for someone's name, someone's name is Palki name is saumya someone's name is john ok I am looking at the names of many students I am someone's name is Prasad, Srishti is Karan If there is a victory then it is in your name just like that Even compounds have names, students we will learn their name because these Now this is a topic of discussion for me I will show you that these are almost as good as 12th class students You have to do the chapters, right? Did you do well in all of them? It is Accept Your Bio Molecule Wala Chapter right then beta isomerism which Your topic is going to cover this as well We will also do many chapters of 12th If you read the topic in Hindi then if you forget it now You must have read that the base is ready from 11 itself So [ __ ] will happen there in a jiffy To the next part is General Organic Chemistry Now I will tell you son when

6:21 If a child comes in 11th then he only He can only do this much, after that he doesn't get tired. goes and the GOC who is very I would say import makes the foundation organic that if he skips it then we will skip it too We will see if there is flow or reagents what is an electrophile what is a nuclear file these things You will understand, right? yes mam please take my name yes sir Aaron Alright, let's get started now Look ahead, like I told you There is a connection with 12th 11th has a connection with 12th is your bridge na so what about 11th This part will be useful in class 12th, listen carefully I have read some of your chapters in 12th here It is written as Halo Alkanes and Organic Lorin, the first chapter of organic to you after that you will get alcohol phenol and

7:06 Ether second chapter organic to see You will get then it comes your aldehyde ketoses And the chapter on carboxy acid is beta After that you have Amindia Ma'am, IUP PAC will be needed for this Neamine will be required for this Isomet J We want more GOC, these three parts are needed I will tell you at the beginning of the chapter How every chapter begins when you A very general pattern will follow in 12th You will see I am saying it again, bio molecule what would be the pattern except son every In the chapter first comes the introduction then Classification comes, then its nomen

7:52 clutcher comes okay then his Methods of preparation comes next, then physical property then chemical property and then its use application and then it is finished So son, in all these chapters, this topic I have written its 11th portion It is okay, so we will read it clearly Is Well, I told you about it today What topics will be covered in the class Hope it is clear now what rules do you follow Please pay attention during this session Give me the first rule, this is single use notebook please on pages Don't write otherwise those pages will be lost later If you go then you will face the problem which we are going to face today You are going to read any chapter you will pick it up, it will be very useful then you can ever Keep this with you at the beginning of the chapter. you can and you can revise it also

8:38 second thing if it is possible son then 2 minutes Go quickly and apply any three colors bring the pen what is the reason right now we are very we will build all the structures okay so when we I will build structures for you people, right? It will be difficult to revise later oh well i sent bond from here to here that it was sent from there to there so that is why if three It is a good thing if you have colored pens, isn't it? brother, I will give you a good idea take a blue pen take a black pen take a pencil if you can do this much okay please do the second thing like this if today we If you want to get youtube4 done then please do that I definitely need to participate actively It will look good ok Let us first talk about organic chemistry let's start what do you think bro Your organic chemistry is according to what you think son What would be organic ma'am it is very common If we talk in the language of organic

9:24 Inside we say this brother of carbon The study would be called organic chemistry Now look, I will give you the very basic definition I am not telling it here because I If you want to strengthen your base then I I'll tell you what things you need do you want to study or not do you want to study It is also important to work smart I said carbon and its study maybe It is organic, it comes to our mind because ma'am every time you use carbon do you use the word carbon And what do you think could be organic tell me chemistry many kids chat Writing in the section Study of Hydrocarbons are classified into organic chemistry What's the matter, son? You said a word. spun material which we call Hydrocarbons What do you mean by this word now? You can divide hydro into parts means hydrogen carbon means carbon what

10:10 Only the study of hydrocarbons it's called organic chemistry or The statement is partially correct etc. Is tell me what you think son the study of hydrocarbons and and and Its Derivatives Beta hydrocarbons and their derivatives What do we call the study of organic They say chemistry now look at the MSc level But if I take you to a little higher level, If I take it with me then there will be many things in it These are the definitions of organic chemistry It did not come very simply, generally it was said It was that brother first started with plants and animals was derived then it said a inoff Nick does not even derive from the compound but various scientists came and He also saw these organic compounds An organic compound was discovered

10:56 So it has a very long history But yes, I will say again what we It is a useful thing, we just have to keep moving on it You should know this much right now that it is organic what is chemistry beta hydrocarbons the study of and its derivatives organic chemistry says good these What are the compounds called hydrocarbons or its derivatives are called It is called organic compound now maam you The word hydrocarbon is divided into two parts divided into hydrogen and carbon but What is this derivative and how to understand it look carefully at the derivatives if I say ch4 is this your hydrocarbon Write yes or no and let us know in the chat section Brother, tell me, tell me, where is the enthusiasm from the quick? Yes yes tell me can you tell me this is your ch4

11:42 Hydrocarbon is good or not absolutely yes ok now if you accept this ch4 Should I remove one hydrogen from it, son? What did I do ma'am I took one of these I removed the hydrogen, well instead I put If I put o group then tell me now what is this Derivatives of hydrocarbons What happened is that it is a derivative of hydrocarbon What exactly happened is that the meaning of derivative which we can derive from it we can extract yes you can obtain it in this how did you get it from me son a What did you replace the hydrogen by removing it? I created a group so what happened to me now? mine derivatives of hydrocarbons and that too which hydrocarbon g ch4 Did you understand the points or not, well I will do it like this

12:28 If I write an example in front of you ch3cl Is it a derivative of hydrocarbon or No, we will tell you everything in the chat immediately I'm sorry, my throat is a little sore, I'm really Sorry, yes, tell me, yes, it definitely happened what happened, what happened here also see If one hydrogen is removed from CH4 then by doing it will be cl1 meaning we will study all these what is organic chemistry called and what are these compounds called is called organic compounds let's We found out that organic compounds what happens maam I understood that a The compound is classified as an organic compound Brother, we need a minimum of one to put in carbon and hydrogen are required It's a simple matter, you only need carbon

13:14 Understanding the points of carbon and hydrogen It is very important to have hydrocarbons Now the question arises that it will be done maam I understood this but You know right now I am in front of you all. what have I done I did PW I'm wearing a t-shirt when I get home I will be in my comfort zone when I am at night I will obviously wear a suit at night Let's put on a suit next day, suppose if If there is a family function at my home then I I will wear the attire according to that If I put it then it is same Shaurya and different different tyres have different tyres which means you You can represent me in a different way yes i am different from myself I can represent you if I get an office If I have to go to the office then I will go there I will wear office wear if you call me If you ever want to go traveling then I will wear clothes accordingly for trekking If I have to go then I will do it accordingly

14:00 Son, when you see the same compound differently I am in different different forms if I keep it then what will happen to her Once the representation is done, now we are going to do it what is the representation of Organic Compounds The same compound can be called as Who can represent you in four ways? There are four ways to show you the screen It is already visible but I am going to give you a still Explain this thing with a lovely example I would like to explain a compound I am taking the example which is mine what is going to happen c4h 10 everyone pay attention Children will see the name of the first representation what is the name of the molecular formula Now this is the molecular formula of the son ma'am what is the molecular formula which the formula of the molecule is the same It's a molecular formula, brother, there's something in it There was no one who could understand the molecule

14:45 The formula is the same as the molecular formula Ma'am please explain this through some examples Just wait a second son, if I tell you this inside your compound is there any number of carbons or hydrogens or any The element present is its exact number Son, if you write on his feet then what will he do It will be called the molecular formula How do you understand this? See what I did. Four hydrogens were written at the foot of carbon what did I write on the foot of g 10 What did I tell you in this compound There are four carbons and 10 hydrogens, so when I am telling you the exact number of the What element will become ours? Will everyone have the molecular formula The molecular formula is so clear If it is clear then we will write yes, yes molecular

15:32 If the formula is clear then all the children are yes will write ok yes right now son ji this is ma'am ma'am don't give me any other way to do the compound If you want to represent then the next way is What is meant to represent is that what is condensed structural formula condense structural formula now ma'am in this What should I do son, you don't have any bond in this Now we have to show you what bond means It happens, think about how many students you have in your class The kids are fine, as is Shalini. that I look like I'm on the edge I am saying there is some small don or Mangala Tripathi is Janvi, I say this I have a lot of favorite students okay And it grasps my things very quickly. we do it, we study well, it's good When they bring the score, it is mine and theirs what will happen bonding will be good

16:19 It will become strong now suppose this of ours Some spammers come into the session okay now If the spammer has not come to read then our If the bonding is not good then this what is the term bonding what is the term bond basically here the word bond means you'll know in a little while when there is sharing of electrons or if the electron is transferred then Different types of bonds are formed okay now i'll tell you about the bond here can you say this ma'am there is a thread is a bond a line or a plane Can we see him like this or not? If you can see it then son, when you copy Bond that is when you write it in 2d representation If you do, represent it with a single line If there is a bond then son one line If you have two bonds, then son, you will make two If there are three, you will make three bonds in this manner

17:04 Do you represent me here now? try to understand when i am saying You also tell me this same molecule in condensed form If you want to make it in structural formula then maam How do I make it here and just be here Shows only carbon and carbon bonds I will first tell you how many carbon meters are there? one two 3 4 this much work should be mine First, I wrote down the four carbon atoms. ok now what should i say mam Which bonds are to be shown? Carbon to Carbon So what should I do in these one by one lines like this made I will not go further, this is all It's okay now son what did I say Showing only carbon-carbon bonds ma'am this means that you wrote 10 hydrogens what will we do with it son, as it is

17:51 I will write it down, what will I do, as it is ma'am, as it is How will we write this, look ma'am what do we know two will come on this, three will come, one will come Now see how much it will cost A carbon son always forms four bonds Remember, tie a knot in your life carbon will form four bonds so if I talk about Let me tell you about this carbon atom, son Everyone will tell how many bonds have been made How many bonds has it made? Everybody tell me how many bonds you have made There is a quick chat section A bond was formed in Son Total Carbon how many bonds does it make four has made one how many are left tell me how many are left How many are left, my son has already made one

18:39 three out of four are left right, so these three We will write hydrogen as it is good How many bonds has this carbon formed in one go One here ma'am how many bonds are left to make four There were two, I have made two, now there are two left Use hydrogen, good or carbon also Maam I have made two bonds, if two remain then two hydrogen and three will come here so what happens Ma'am here the bond is only carbon and Hydrogen is shown between the carbon atoms We put it as it is so its name is what is condensed structural Is the formula clear to everyone? Is it clear to everyone, tell me ok like Just like Palki Jain has written this comment in section ch3 ch2 ch2 ch3 son i am wrong I will answer this question if I ask you If she is a teacher then what is the reason because son

19:24 You didn't even show the bond it's directly written ch3 ch2 ch2 bond It is necessary to show, I said show the bond It is important to listen carefully to what I tell you I am telling you things, okay now son let's come on which formula the next one which Representation is what is called Expanded Structural Formula Expanded means even more expand it and write more than this brother will you expand the carbon You showed me the carbon bonds, ma'am of hydrogen is left that means son when You will write the bonds of all the atoms openly If you represent all the bonds then they will be yours Expanded structural formula will be Is this thing clear to everyone? Tell me What will come here ma'am it's a simple matter

20:09 First we drew this condensed Now let's make it condensed once again Look how many we did with this carbon Brother, apply hydrogen, apply three hydrogens How many are three ma'am? If we put three then all three show them all three ma'am this How many bonds does carbon have? Two I want to apply Hyde Rosen brother please do two shows ma'am do two shows of this too do two shows of this too Do a show of this too son, now this is 2D Representation is when you see these actual you will see like this ch4 molecule look at these Does it actually look like this? Do all babies get this? can you see look carefully what all Students are able to see this thing Clear in actual son it is like this The shape is a carbon here is one above the other

20:55 here one here one here when we write it in 2D So on one carbon we have four hydrogen atoms that show or show bonds This is how they show it actually This is what it looks like now when you are in class 12th if you will come and study in class 11th then this introduced you to the structure of the method will be introduced to the beloved cute cute structures aren't they ok hai very good ok can someone tell me What is this shape, what is this structure ch4 is of methane okay this is our carbon atom and the rest is all hydrogen No tell me what is the matter yes exactly Very good son very good this is not it You all read about this in class 10th also. What about intelligent children

21:41 it's a very very good thing here Let's come to the line notation, very correct son what is it , madhuja is absolutely right It is true for Amandeep and it is true for Siya too. Aayushi sahab all is well very good now Listen to me carefully, you have the same The structure is represented in a way Now the most important thing remains which is to have children How do teachers confuse children? I will do it brother, when you come to 12th, son If you come to 12th then do you know what teacher The teacher will say this by reacting Now show me what have you made, what is it this here you didn't show any carbon You didn't show hydrogen here ma'am Maam you are confusing me, this is something else Son, I have made this the bond line What do you call notation, son?

22:27 bond line notation says mean mam Bond line notation means when the bonds are marked with lines You directly wrote in the form of without representing any element son neither Will you write 'C' for the word carbon or not for hydrogen? h you will write it and you will not write anything else Only through bonds can you understand things I want to show you now how to show you ma'am kiss I want to show you how to do it, tell me a little Just took an example of c4h 10, this mam how to do bond line na how to do it Represent ma'am look how many carbon four carbon son now to explain it to you no, I will put a dot just to explain ok i am just saying that to explain So I am actually putting a dot on the copy there should not be a dot ok one single

23:15 bond second dot then second bond third carbon and this fourth carbon look carefully Son, the number of dots you have put also means this this is carbon this is also carbon this is also carbon and this is also carbon, are you understanding the point? After that you have to fulfill the valency brother mam comes this has created a bond Carbon forms four bonds with three hydrogen this is it won't it will be connected to this so this is ma'am Things come to us but there are many things in you. Do you know what the kids are thinking ma'am Should I make one tooth four, what did I even say Students, you should not put a dot here. So if I remove the dot, it will become single The bond is formed, so this is two carbons If you want to show four then this son is like this

24:01 or you can make it like this whether you understood the point or not, that is when we I tilted it so that there is a brother on every corner you must have a carbon did you understand the point or not what do you call this The bond line notation says done It is clear when only bonds are passed through Representation happens, it's ok, son it is clear ok ok ok look at this Now let me repeat it once again What is the molecular formula when total The number of atoms they represent molecular formula is when all the If the bonds are shown then they will be expanded When there is only carbon of carbon then it is condensed and in the bond line you just have Show the bonds, only show the bonds

24:48 What has to be done, is everyone clear on what it is That's great so let's move on to the questions What do you want to do quickly now, son? You also have to tell about these border line notations What is the condensed structural formula of will be represented in a quick way Everyone will open their notebooks and type in the questions. will solve the following represent the following Structures in the Form of Condensed Structural Formula Tell yes yes Everyone will be represented quickly then we Match will do it tell me what is the matter very They are intelligent kids, let's see, son Yes, I would write it here like this

25:34 huh son one carbon one carbon now look at this What we know about Condense Structural only carbon in the formula Bond ma'am has to be shown to the rest hydrogen as it is to me is carbon ne one bond made carbon four makes three The rest is three hydrogens with this carbon formed a bond to carbon makes four three left, three hydrogen together, so what is this? What happened ma'am this is ch3 single bond ch3 what This is a great thing in the chat section I can see that Manpreet Kaur is right Shreya's statement is absolutely right Himanshi ji yours The answer is wrong, after this A Deep is yours too It is wrong, well Deep probably asked the second question Himanshi also did a second, very good ok what's the matter what's the matter let's go If we look at the second question, son Can you also look at the second question here? this is carbon this is carbon this is carbon

26:19 one carbon has formed a bond with four Three have to be made, the remaining three are hydrogen this carbon has one bond here, one bond there and two bonds there I have made it ma'am carbon makes four makes two two are left so two hydrogen together Ma'am this one has made a bond, there are three remaining three hydrogens together in other words mam i Can I represent it like this? It is clear to everyone Yes Nandita's is right, Madhu's is absolutely right It's absolutely right Sangeeta is absolutely right Subodh's is correct, Dhruva's is correct, Aayushi's what is it right anupam what is it Children are also giving them very good names Looks like let's move on to the next question Students solved these questions very quickly will do third fourth question on your Answer quickly on the screen what do you think What will be the answer, tell me brother what do you think what will be the answer

27:14 yes quickly say everyone lets what's up you guys are very good Nemin is also doing it, I liked it very much dear Now let's see in this case ma'am There are many simple ones here, I would use some other color so let me show you a carbon mam here There will also be a carbon here, there will be a carbon here one here one here ma'am this carbon has a bond one carbon forms four bonds one has made three, remaining three are hydrogen ma'am this carbon will also come with a A bond is formed Four bonds have to be formed One has made three, same thing with the rest Maam it will be good for this also Will hydrogen be available on carbon or not? All the children from the center will be told in the chat Will carbon get hydrogen or not? I will get this Tell me whether I will get it immediately or not

28:02 You will not get it at all, son made four bonds if it is already there then where will you get it from then son you can also write it like this ch3ch ch3 ch3 ch3 is it clear to everyone things are good very good very good thing Let us tell you the fourth case. ma'am what will happen in this case oh my god this is This is a question that kids get wrong Do you know what their minds do? What is going on ma'am, carbon is here too also carbon here also carbon here also carbon wrong son wrong there'll be a carbon in a corner Always remember there is a carbon in a corner I mean to say that this whole part is a This whole part is a carbon It will happen like this now son this carbon has two bonds One carbon has been made, two makes four

28:49 How many have you made yet? The remaining two are here But what will come, yes ma'am, two hydrogens come ma'am if you go and see this carbon then there is a bond here two bond here three make it four makes one remaining then one hydrogen will come Well look at this carbon and make one brother If three are left then this will happen to it like this can write ch2 double bond ch single bond ch3 what do you say bro tell me clear ma'am it is not available in center carbon yes absolutely right Rathi na absolutely right ok okay what's the matter it's okay let's go ahead Moving on to the next question, son, next question hey wow again interesting question triple Bond's case has arrived, tell me to triple it quickly

29:36 Bond's case has arrived, please look at it quickly You will get one question for each case so that your every Let the concept be clear, tell me it is a single bond The double bond is gone and we are on the triple bond People have arrived yes yes everyone tell me quickly what you think what will be the answer to this don't do it like this now brother, I am telling it beforehand like this Don't do this, this shouldn't happen, this is wrong This is the way, isn't it? This is a very wrong way, ma'am. This is a complete carbon, this is complete the whole second carbon would be a carbon ne mam three bonds are made to carbon four making a Rest one hydrogen will come here also one will come will go from triple bond to tell organic I am still scared, tell me, tell me, you will say it Maam this topic looks good, let's move on When the reaction comes, there is no fear yet

30:22 Are you feeling it or not, tell me now Did you feel it or not? Did you feel anything like this till now? also the one who has troubled you It seems like this, friend, please ask me questions like this it's in the paper no good tell me this now this is the same mistake which you can do it here you can do it here too Son, whatever you can do here, you can do it here too What mistake can you guys do with this son? don't do it like this, it will be wrong, okay how would this be one carbon one carbon one carbon will be a carbon then this carbon one bond is formed so three hydrogens here also three good this carbon has made 1 2 3 variable so how do we write it ch3 c triple bond s ch3 no doubt no Tell me any doubt, brother

31:11 No problem, it's very intelligent Children are brothers, nomenclature in chat Tell me what do you think cyclic means First of all it is necessary to tell about the cyclic So you started from one corner and It is the last carbon and gets attached to it Went tell me tell me tell me tell me quickly what do you think mam it is simple mam here is a Carbon will come here A carbon will come here too It will come here too ma'am this carbon has given another Two bonds have been made, two more can be made ma'am This carbon has formed another two bonds. And ma'am this carbon can also be made into two

31:58 Bonds have been made two, this one can also become two We have made it, if this can also be made then son what will happen ch2 ch2 ch2 ch2 and this is done It's clear, okay now what is this, son? What is carbon? Let's see this as well carbon carbon carbon carbon carbon carbon How much carbon How many hydrogen atoms are there in hydrogen? Two hydrogens will come, tell someone In case of any doubt, representation on next topic All of you will do the representation now It will happen brother, representation will happen, right?

32:43 Tell me it will be done, we will move ahead Shaal V Let's start with the next part good very good son now I will tell you I am going to tell you about Bunds and Hybridized try to understand this in the language I am telling you as much depth as you want to know You can see two types of Beta Bonds here you are going to have a sigma bond which you write like this and one of yours There is a G Pi bond which you write like this ho ok he will understand if i make a single bond I'm making the same line and taking one I'm taking a case of the double bond I'm paying attention to the triple bond now Understand the meaning son, if a single bond is being formed always keep in mind that this is the first bond it is a sigma bond what did you say

33:30 The first bond is the sigma bond It happens ma'am when you are creating a double bond then first bond sigma second bond pi It is definitely clear, look below maam What will be the first bond in a triple bond? sigma second bond pi third bond also Pie Clear The first bond is always a sigma bond The rest of the bonds are formed later, which there are bonds okay good one more thing Son, there are two electrons in a bond Always keep in mind how much a bond is worth electron son g two electrons good Now tell me one thing, how much will the bond be? there will be electrons then if there are two of one

34:17 Two will be four ma'am what is this Maam you are asking very simple questions. Maam how many triple bonds are there electron 1 2 3 4 5 6 six electrons ma'am tell me will you do it, what is the matter Ok, this is about G Bond. What you wanted to know is whose turn is it now My son is hybridised If you can tell their shape because of this then these are hybridised how do you calculate it son Hybridised Brother Sigma bonds to count and loans We have to count pairs ma'am sigma bonds so

35:02 You told me what a loan payer is, son, loan What does pair na pair mean? what does pair mean give it to me son It will look like this, what is this loan pair means two The dot where two dots are attached It means two electron what do we call this loan pair so son whenever you hybridized I want to see how many there are and I want to see loan pairs Add them, if son, how much is their amount If you get G4 then your hybridised Hybridized If it is settled then we are talking about carbon Well if they get even three then Hybridised There will be an EGE now tell me how to remember it

35:49 It has to be done not like this, it will be done on four but on three There will be two, this will happen, that will happen, don't do it like this Look, just use your mind a little here. A and what will be 3p if it is four then it is four one a and two p how much will it be three will be one a and how much will one p be it will be two but but But look carefully at the Pi Bond, son Have you ever hybridised No respect for poor Pi Bond we are giving, look, we are not giving only We are telling Sigma Bond that brother we will look at that and look at the loan payer Pi Bond get out of there Pi Bond Hybridised it is solid it is clear okay go ahead I'm moving forward now we're doing one thing

36:35 Take care of hybridised You are studying organic kids, who knows? it should be maam please note down the things if Negative charge is written somewhere there So son, negative charge means you have a loan You will take the pair only because of the negative charge It means there are two electrons, what would happen the other thing is that it has two electrons I am going to tell you an important thing says that if you have a negative charge or The loan pair is present on any carbon which is attached to the double bond listen to what i said if negative Charge and loan pair is present on the Adjacent to the double bond what is this double Adjacent to the bond

37:22 what is it with this one, it's negative son Hybridised that lone pair is hybridized Explain ka and pi bond here first I will give you a simple question I tell you how to calculate sigma bond Answer of ka and pi bond in all four cases by doing tooth 4 you will write well one thing i And let me tell you about this case which you need to look into Are you getting carbon then it is written c a Son, this wouldn't have happened in C if there is a triple bond then it gives four

38:09 If it happened then it is like this Son, I understood it, now tell me here To calculate sigma bonds and pi bonds Brother how many sigma bonds how many pi bonds we will do it quickly we will do it all quickly Child ma'am look here by opening it ma'am it would be better to write on this ma'am three There is hydrogen brother on this so there are three on this too The sigma bond is the first bond son see one two 3 4 pa 6 and seven maam There are seven sigma bonds and zero pi bonds Is Right, what a thing, let's see this case. yes ma'am ma'am we have said the first bond Sigma is one 2 3 three hydrogen

38:55 how much will be six six together with this 7 8 8 and what is th 11 mam 11 sigma well how much is the pi second bond pi bond So ma'am there is one pie bond, tell me what is it yes son, ok let's look at this, let's look at this Let's first bond sigma first bond sigma two sigma this is two hydrogen four and five and six mam is six sigma bond How many pi are there son, how many pi bonds are there two paise is fine brother, it would be better if you come here yes mam one two three cha pa 6 sa aa eight sigma pi how many are pi Vat 3 fur 5 6 7 8 8 pie bund

39:43 tell someone if there is any doubt in anyone any one that's why i said some colorful colors Get a pen and life will be colourful Why should life be black and white? I want to live, I want to live a colorful life Don't say anything brother, everything is clear what's the matter easy yes it's very easy Did you understand the question? Let's move ahead. Yes ma'am Now, son, we have seen this here. Now comes the turn to pay attention to this question You will see three structures in front of you Given is the beta given in bond line notation Do you want to tell me how many sigma bonds there are? Now this question is very important how many pi bonds are there It is good, son, two such carbons whose Hybridised

40:40 Tell me how many sigmas are there between Yes, student's life is black and blue It works with a pen, generally a blue pen it's just going on tell me tell me tell me quickly say everyone what's up brother very good very good You are answering very well let's see Are you right or not? Please check. Yes yes mam look son first thing is this Convert it into condensed, just do a little work It will become easy now, see, you just learned it condensed So I applied here, there is a similar connection Son, okay, here it created three bonds. there's one hydrogen left over here three will remain now everyone will pay attention to what I say ma'am we will see here we are counting sigma

41:27 isn't it, so here is one ma'am, two three hydrogen So it became five, six, seven and eight ma'am here How much is Pi One ok to listen to the next question He says firstly two sp2 hybridised Look at the carbon atom, brother, tell me something. How many sigma bonds did this carbon form? The pink one which has been underlined Hybridised yes yes Isha ji hello hello yes yes Dhruv it's a good thing son it's hard work that's very good ok see you soon Physical is still going on in the Parshram batch after that it is organic chemistry We are going to meet, let's go quickly Well Sakshi is writing SP is Angel

42:13 Arora is writing A2, Shrikant is writing are A2 Himanshi S3 Sakshi A2 ok ajab SP is writing, you are definitely right friend People have to count the entire Sigma bond of this carbon ma'am please make this one Sigma Three have been made with hydrogen as well I am not going to count these pies ma'am what happens at three sp2 means this carbon How is it son, is it sp2, right? Yes, ma'am, it's good. This carbon has one hydrogen one here and one there I don't need to count pi ma'am it's three also which is sp2 hybridized atom is ok ok look son he has one here and three here Here he is making four for four sp2 3 What is the question? What happens between two sp2 atoms?

43:00 brother tell me how many sigmas are there between two sp2 has the same sigma Maam the first question is clear, right? it is clear son yes it is definitely clear let's go here now Let's look at this case a little bit. no i will make it broad you guys It will become easier for me to do something a little better okay well now look carbon carbon carbon carbon carbon carbon carbon carbon this carbon formed one bond, then three Hydrogen 1 two four no hydrogen one doti one hydrogen will come one doti one hydrogen will come one hydrogen will come one One will come here too, it is clear to everyone

43:46 Good yes ma'am namaste ma'am your two years ago I am reading the video maam thank you so much Prana, thank you, everything is fine son, for now Thank you very much for paying attention here your look good talk about sigma bonds so son one two three five six seven its ok After three this becomes 10 i.e. 11 12 13 14 15 mam 15 sigma bond is 15 sigma bond is pi bonds how many so one two more Ma'am there are three pi bonds now it's your turn son Understanding sp2 hybridised carbon atoms If it has been done then let's see it brother, see sp2 ma'am This is sp3, it is forming four bonds ma'am

44:31 If you look at this, 1 2 3 this is sp2, son this too it is sp2 son, this is also sp2 son, this is also it is sp2 son, this is also sp2 son, this also sp2 how many sigma sp2 between 1 2 3 4 5 6 Maam it is clear to everyone it is clear for sure let's go ahead ok One question will be homework for everyone today ok let me tell you the mistake here what do kids do This car, this son will also make a car, right? don't be confused son this will be homework when When the session ends, you can give me the answer Enter your name and city in the chat section and you have to write your answer okay yes so much Nana Bhai, I am able to interact wittily

45:17 Also we should know from which section the children are studying yes right okay so this is the first time in your class the question will be yes as a homework right is clear Ok let's go ahead and do it after one day son I will answer this in the chat section I will get it pinned, it is sorted and then the match too you will do it, move on Ok, I have drawn the structure. Now son we are going to do a degree Of carbon brother carbon tells me too degree is needed jokes part degree of carbon If I talk about it then son carbon there are four degrees what are they mam Primary Carbon Secondary Carbon Turp Carbon Quartan Carbon Beta Primary

46:03 You can put carbon in one degree like dots like this You will write carbon by applying 1 degree carbon also The secondary carbon is called beta ji like this two and above it put degree like this you will write it for carbon it is written in these Same way son, we can cut terz carbon like this 3 you write by carbon degrees and You can write quarter carbon as 4 degree carbon will write it after doing it, isn't it correct, now ma'am 1° What is carbon, son, such carbon which What did you say if the particle is connected to the same carbon? I have created a carbon which is a single carbon be connected to see this carbon is from the same It is related to this, you should complete the valency By adding hydrogen, this carbon becomes the same Maam this is also connected to carbon 1° and this also If it is attached to the same 1° carbon atom, then it is also

46:50 what will happen did you understand ok mam if one If a carbon meme is attached to two carbons then son that would be 2° if one carbon son three if it gets connected to then it will be 3rd degree if one If carbon joins with four, then son, that is 4 It will be degree carbon, okay, yes, yes Pranav your NDA interview is good, all is well The very best Pranav, you have to do it well No and the rest is your hard work and your dedication No, she will definitely want it, it is okay and best The results will definitely come, ok ji all the very well best son good rana ok very good thing ok now look at the secondary carbon Let's see, suppose I give you this case Gave Son, tell me in all chat sections son If this is first, this is second, this is third

47:35 if there is carbon then first second and third carbon What degree will the atom be in the chat section tell me which one is first, second or third The carbon atom of the degree will burst burst burst burst Everyone tell me quickly what do you think tell tell Tell me, tell me quickly, son, quickly Our first part is coming to an end. After this we will look at the IUPAC nomenclature will start it in a little while ok Our first part is about to finish So please answer me quickly, tell me Tell me son what are you writing on first carbon are all first carbon primary what about yes son it is attached to the same carbon so This 1° carbon is so many carbons It is connected here also, ma'am, it is connected here also It is connected ma'am this is 2° and what kind of carbon is this 1 degree what is it clear very good

48:24 very good well now if carbon is your further if it was attached to three carbons then what would it be? it is 3 degree carbon yes mam ok i will give them my number here So you tell me which carbon atom no don't tell me that yes wait a second son in this case 1 How many degrees are there in carbon atoms? 2 degrees How many carbon atoms are there and 3 degrees carbon 1 degree tells you how many atoms there are How many carbon atoms are there in 2 degrees? And you have to tell me quickly how many degrees there are in 3 tell me quickly what do you feel Tell me how much is 1 degree and how much is 2 degrees

49:10 There are 3 degrees, I will tell you quickly how many there are yes everybody son it is connected to the same one so this It is 1°, this is also connected to the same, this is also 1 This is a degree, this is also connected to the same thing, ma'am If it is also 1° then 1° so ma'am there are three 1° how many yes ma'am three is good 2 degree ma'am who it is connected to two ma'am it is connected to two yes ma'am this is also 2 degrees so 2 degrees ma'am It will become two, okay son, 3 degrees how much yes son this is the same 3rd degree which is different from the three If it is connected then 3 21 is the answer 321 is the answer beta 3 21 answer hai tell me what is the matter brother ok now 4 what is degree carbon son when carbon bonded to four carbons such as this Look at the carbon, this one in the center It is carbon which is connected to four carbon atoms So this is of 4 degrees, does everybody get 4 degrees?

49:58 Degree Carbon Clear is Primary Carbon Secondary tarry and quarry carbon is clear tell me if it is not there then let's go ahead with degree Move on to hydrogen if it's clear to everyone is yes everybody come on now son degree of hydrogen come on degree of hydrogen what are three There are three kinds of degrees, son degree is primary hydrogen Secondary and Tert Beta Quarter Hydrogen Quarter hydrogen does not exist doesn't ageist all the kids will pay attention

50:43 now maam how to calculate the degree of hydrogen So one is hydrogen and the other is hydrogen hydrogen is connected to one hydrogen two Hydrogen is connected to carbon like There is no carbon degree at all son If you know, then after that you can do as much as you want. If I ask for your degree in this world, can you tell me? how are you ma'am if i tell you your Hydrogen is attached to the primary carbon listen carefully if your hydrogen is attached to the primary carbon, then it primary hydrogen is if your hydrogen is attached to the secondary carbon then the secondary Hydrogen is if your hydrogen is If it is attached to carbon then it is tert hydrogen Will you understand the point or not? Understand Tell me look carefully if I give you this Yes son, in this case the first thing is the degree

51:31 Look ma'am this is 1 degree carbon this is also 1 degree carbon this three hydrogen this primary These are not related to carbon Hydrogen will also be called 1 degree If you say hydrogen then I will ask this how many 1 degree hydrogen in the molecule is you will say ma'am six is ​​you will say ma'am six yes, what is 2 degree hydrogen when hydrogen is released from secondary carbon what is the 3rd degree hydrogen connected what is hydrogen brother 3 degrees It is clear on the questions related to carbon Let me come to the questions, if I tell this to everyone it is clear So ma'am when will you come to the Parshram batch All the children are writing that son will come soon Your physical chemistry will end soon. When organic starts after that we will meet there right ok

52:19 okay it's right yes ma'am go ahead ma'am let's go Ask this question. Our first lesson ends here. after that ask me the question i want to tell you I have to tell the degree of carbon and I need to tell you the degree of hydrogen and carbon of and hydrogen Can you tell me how much is 1 degree carbon? how many are there in 2 degrees carbon? how many are there in 3 degrees? How many carbons are there 4 degrees how many carbons how many are there in 1 degree hydrogen 2 how many degrees hydrogen are there 3 degrees How many hydrogens are there and 4 degrees is it hydrogen or not yes tell me tell me tell me Yes, tell me quickly, first of all I 4 degree hydrogen does not exist at all Just cut it, I have done it, now tell me

53:06 tell me now tell me tell me tell me look ma'am Let's make the structure a little prettier Maam make this structure a little beautiful look ma'am here is carbon carbon carbon carbon here ch3 here also ch3 here also ch3 and here h will come, assume that Don't you believe it, okay ma'am, this is the same carbon is connected to 1° this is also 1° this 1 degree so Maam how many degrees are there 1 is three ok 2 Do you have a degree or not? Zero ma'am, not even one it is 3 degrees right here ma'am it is one 4 Even the degree is zero son, now they have a way Count it like this, is it not a third or is this one too the way is a new degree carbon three If there are hydrogen then how many should there be for three If they don't go brother, they will become zero and 3 how much is the degree hydrogen one is one p one if it happens then it will become one, right the first case is all

53:52 to clear Is the first case clear to all of you? okay now let me quickly show you this Tell me quickly about this case tell me carbon carbon carbon carbon carbon carbon carbon carbon ch3 ch3 ch3 ch3 ch3 ch3 ch3 right sir ok mam 1 degree carbon How many are there 1 doti 4 pa and six mam 2 degree ma'am there is not even one 3 degree ma'am one There is no 4 degree mam two so here is 1 how many degrees hydrogen will g 18 and all other values ​​will be zero

54:38 it will go, it will become zero, what do you say brother what do all the people say yes quickly tell me it is clear son degree of carbon and We will do hydrogen, we will do it quickly Tell me then let's move on Now delete this question number. It is okay to do it because previous questions I did not count which question the number was ok listen carefully now i I am going to tell you about my degree of alkyne halide which will be your topic In your very first chapter, which is called Hello Alken and Hello Ares now I will tell you this I am telling you the topic which is for this chapter of yours

55:24 I will come to what is called halo alkane and Hello Arin son here is alkyne halide which I wrote the word alkyne halide which I have written the word, its other name is hello What is an alkane? What is a halo alkane? Hello not the alkane one, this is simple hello It is an alkane, what does it mean first Understand, I will give you a small hint, son. Did you just see the hydrocarbons and their What do you call derivatives? Organic It is called compound, if suppose I have this son one of ch4 from methane Hydrogen was removed and some halogen was added x installed x is to install halogen so that is yours what will happen ch3 x will become x means here You can also take fluorine or chlorine You can take bromine as well as iodine You can take it, these are halogens, son, right?

56:09 So the compound that is formed is called hello alkane. You say that you have understood what you get from alkane What is derived from alkane? You have got a driver, now see this How will you tell me his degree, son? have to do it like we used to do with hydrogen how did you do hydrogen ma'am if our hydrogen is attached to the primary carbon primary hydrogen if our carbon is connected to secondary hydrogen then Secondary is connected to tersh is tersh is no you have to do the same here as well with your halogen The degree of the carbon to which it is attached is the same If it happens then let's see here, son, this is ours A halogen is attached to a carbon which is is attached to the same carbon, that means our If halogen is attached to primary carbon then it The compound is our primary alkyne halide what will happen will it become primary alkyne or I can also call it 1 degree alkyne halide I will tell you, understand the point, good son, this is

56:56 look at the question mam this bromine is The degree of this carbon is connected to carbon what is 2 degrees is 2 degrees so if Son, this is 2 degrees so this is your alkine What halide will become a secondary alkyne What will happen to Halide, son? The secondary alkyne halide will be correct Brother it is clear, ok ma'am this is chlorine this carbon is attached to a carbon bond that is attached to three carbons It is connected means mam chlorine 3 degree is attached to carbon so this is our alkyne The halide will become a 3rd degree alkyne halide As for bromine, please tell me like this Maam will keep telling you all when Will you tell maam what will be the answer to this Which one is alkahalide? Yes, which one is alkahalide? lie hai yes everyone tell me quickly chat Brother, you lower your spirits in the section.

57:43 Did you go so quickly, did you lose so soon? Speak up, speak up, you lost so soon What yes sir tell me nawa please take my name hello yes G 2 ° 2 ° Manpreet Kaur Six why are you writing six son 6 Where did you start getting your degree, which 6 You got your degree bro Yes, your enthusiasm wanes, my friend.
