Test Preparation

My plan for the chapter Alkenes is discussed. The no. of videos will be 15 and there will be many important reactions covered in the chapter.

Course Overview

Rosenmund's catalyst, Lindlar's catalyst, Birch Reduction and Hydroboration of alkynes to alkenes are discussed with many examples in this video.

Reduction of Alkynes to Alkenes

We discuss dehydration by E1 mechanisn and many examples citing the mechanism of carbocation rearrangement and ring expansion.

Dehydration of Alcohols by Concentrated H2SO4

The very important Saytzeff and Hoffman elimination are discussed. E1,E2 elimination's basics are discussed. Al2O3 and ThO2 are discussed.

Saytzeff and Hoffman Rule, Dehydration by Al2O3 and ThO2

Alc. KOH and TBuO- are differentiated. The importance of changing the different halogens is shown in gaining a Saytzeff or Hoffman as the product.

Dehydrohalogenation of Alkyl Halides

This is a comparatively easier topic but we discuss two very important questions here by the end. Dehalogentation of viscinal halides can be carried out by Na/Et2O or Zn/Et2O or Mg/Et2O or Li/Et2O.

Dehalogentation of Viscinal Halides

We discuss Wittig's reaction here with many examples as it is one of the most important parts in Organic chemistry. It is used for the preparation of alkenes.

Wittig's Reaction

This is a very important reaction from the JEE Advanced point of view as we can prepare Alkenes from this method abd moreover, we use this concept in class 12th too in the Amines chapter.

Pyrolysis of Quaternary Ammonium Salts

We discuss the pyrolysis of esters and Cope's reaction in this video for the formation of alkenes. Both of these reaction mechanisms are very important as they follw a concerted mechanism.

Cope's reaction, Pyrolysis of Esters

What's the difference between the reaction of HCl(gas) and conc. HCl? Let's learn it in this very exciting video.

Hydrohalogenation of Alkenes

The very important differences are discussed between:
1) HBr
2) Br2/CCl4
3) Br2/hv

Halogenation of Alkenes

BrCl, ICl, BrI etc.
Let us see that what's the reaction mechanism behind these reagents and how the varying of a cation and anion affects the product.

Interhalogenation of Alkenes

We discuss the concept of HOX attacking the alkenes. We discuss very important questions at the end of the video about the Hemiacetols and tautomerisation.

Reaction with HOX

B2H6 and the use of NaOH/H2O2 is discussed for the production of alcohols from alkenes. We discuss a previously discussed question also so as to clear the doubts.

Hydroboration and Oxidation

We understand the difference between Dil. H2SO4 and Conc. H2SO4. The reaction mechanism for the hydration and dehydration has been discussed with examples.

Dilute H2SO4 (Hydration)

We discuss some important questions for the chapter 'Alkenes' in this video. It's the Part I of the two video series.
There's one question in the video that I've deliberately done wrong so that I can know if you are following the video properly or not.
(Hint: Regarding alpha hydrogen)

Important Questions(Part I)

The very important concept of *Ozonolysis* is discussed along with many examples.

This Course is an extension of part 2 hydrocarbons in which we will study Alkenes

(Hindi) Hydrocarbons - 3: IIT JEE

In this course, the educator is discussing 
all the concepts of the basic organic chemistry and hydrocarbons for IIT JEE aspirants

(Hindi) IIT JEE: Hydrocarbons

This course is the first part of the unit 'Hydrocarbons'. The real organic chemistry begins with the chapter Alkanes where we shall deal with all the reagents and the mechanism for the reactions.

Alkanes for IIT JEE

The third part of the hydrocarbons 'Alkynes' where we initially discuss the preparation and later on move on to their reactions.

Alkynes for IIT JEE

In this course, Sachin Rana discusses Dienes. He takes you through its important reactions, including Diels Alder Reaction.

Alkadienes: IIT JEE

In this course, we do in depth analysis of Stereoisomerism and Structural isomerism.
