Assertion: Friedel-Crafts reaction is us...

Assertion`:` Friedel`-`Crafts reaction is used to introduce an alkyl or acyl group in benzene nucleus
Reason`:` Benzene is a solvent for the Friedel`-`Crafts alkylation of bromobenzene.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
Yes, we use Fredel`-` Crafts reaction for introducing an alkyl or acyl group in benzene nucleus. Thus, assertion is true.
However, the reason is not true because if benzene is used as a solvent, during alkylation of bromobenzene, benzene will be alkylated in preference to bromobenzene because benzene is more reactive for `SE` than bromobenzene.
