The mechanism for acidic hydrolysis of a nitrile resembles the basic hydrolysis, exceptthat the nitrile is first protonated, activating it toward attack by a weak nucleophile (water).Under acidic conditions, the proton transfer (tautomerism) involves protonation on nitrogen followed by deprotonation on oxygen. Propose a mechanism for the acid-catalyzedhydrolysis of benzonitrile to benzamide.
