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 the reason is not the correct explanation of the Assertion
• C. If Assertion is true but Reason is false
• D. If both Assertion and Reason are false

Answer 1

Answer: (C)

During alkylation of bromobenzene, if benzene is used as solvent, alkylation of benzene will take place because benzene is more reactive for $ S_{E} $ reactions than bromobenzene, so benzene is not used as a solvent for this reaction.
