प्रश्न
Give example for the following type of organic reaction.
β - elimination
उत्तर
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.
