Elimination reaction in a nutshell

Dear Students,

In this three-hour class, I will introduce you to another important reaction: 
Elimination.

In the previous lectures, you have seen alkyl halides undergoing nucleophilic 
substitutions (SN), for example:

The reason is that halogens are very good leaving groups. A nucleophile attacks
 the carbon to which the halogen is attached causing the halogen to leave.


An elimination reaction works quite similarly, like this: 

The halogen leaves but also a hydrogen is taken away. The hydrogen is taken away by a base. The result is the formation of an alkene, or double bond.


You will see more examples like this in my lecture. In this class, you will learn about:
-  the two mechanisms of elimination, E1, and E2
-  Stereochemistry of elimination particularly E2
-  Elimination of cyclic alkyl halides
-  Alcohols and amines can also be made to undergo eliminations
