• Which statements are true for the mechanism for hydrolysis of an amide? * tthe reaction is a nucleophilic acyl addition. Water acts as the nucleophile in hydrolysis. The mechanism involves six steps. Protonating the carbonyl oxygen speeds up hydrolysis. Protonating the amino group creates a better leaving group by weakening the carbon-nitrogen bond.
