Question

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.

Answer 1

Correct Answer - 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.
