Question

Give example for the following type of organic reaction.

β - elimination

Answer 1

In this reaction, two substituents are eliminated from the molecule, and a new C – C double bond is formed between the carbon atoms to which the eliminated atoms/groups are previously attached. Elimination reaction is always accompanied with a change in hybridisation.

Example:

n – Propyl bromide on reaction with alcoholic KOH gives propene. In this reaction, hydrogen and Br are eliminated.
