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 reason is the true explanation of the assertion.
B. If both assertion and reason are true, but reason is not the true explanation of the assertion.
C. If assertion is true, but reason is false.
D. If both assertion and reason are false

Answer 1

Correct Answer - C
Correct reason. Since benzene is more reactive than bromobenzene, therefore , F.C. reaction will occur preferentially in benzene rather than in bromobenzene and hence benzene cannot be used as a solvent in this reaction.
