Question

Short note on friedal craft alkylation reaction

Answer 1

Answer :

Friedal Craft Alkylation Reaction -

The process of substituting alkyl group over benzene ring by treatment of Benzene with Alkyl Halide in presence of lewis acid are known as friedal craft alkylation reaction.

Benzene + Alkyl Halide $\longrightarrow$ Alkyl Benzene + Hydrochloric Acid

Mechanism -

Mechanism of above reaction takes place in following three steps :

1. In this step the generation of electrophile takes place.

2. In second step, electrophile attacks over benzene ring to give a resonance stabilized carbocation.

3. In this step, resonance stabilized carbocation looses proton to give final product.

Answer 2

it conversation of benzene into its substituted product
