Which of the following intermediates is present in the acid-catalyzed hydrolysis of t-butylacetate but not in the acid-catalyzed hydrolysis of methyl acetate?

Question

Quizplus · Accepted Answer

The acid-catalyzed hydrolysis of t-butylacetate proceeds through the formation of a carbocation intermediate, which is stabilized by the electron-donating groups on the tert-butyl group. In contrast, the acid-catalyzed hydrolysis of methyl acetate proceeds through the formation of a protonated carbonyl intermediate, but not a carbocation intermediate. Carbanions and carboxylate anions are not intermediates in either reaction, and 1-propanol is a product of both reactions.
