Assertion: Alkyl benzene is not prepared in good yield by Friedel-Craft’s alkylation of benzene. Reason: Alkyl halides are less reactive than acyl halides.
Assertion: Rates of nitration of benzene and hexadeuterobenzene are different. Reason: The C—H bond is stronger than the C—D bond.
Assertion: Friedel-Craft’s reaction is used to introduce an alkyl or acyl group in the benzene nucleus. Reason: Benzene is a solvent for Friedel-Craft’s alkylation of bromobenzene.
