Vedclass · Answer

(C) The assertion is correct because Friedel-Crafts reaction is indeed used to introduce an alkyl or acyl group into the benzene ring.The reason is incorrect because benzene cannot be used as a solvent for the Friedel-Crafts alkylation of bromobenzene.Bromobenzene is deactivated towards electrophilic aromatic substitution $(S_E)$ due to the electron-withdrawing inductive effect of the bromine atom.Benzene is more reactive than bromobenzene towards electrophilic substitution.Therefore,if benzene were used as a solvent,it would undergo alkylation in preference to bromobenzene,leading to a mixture of products.

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