Question
Chapter 21.7C, Problem 21.19P
Interpretation Introduction
Interpretation:
The important resonance contributors for both resonance-stabilized cations (in brackets) in the mechanism for acid-catalysed hydrolysis of an amide are to be stated.
Concept introduction:
The mechanism of acidic hydrolysis of an amide comprises two stages. The first half is an acid catalyzed addition of the nucleophile (water). The second half is an acid catalyzed elimination of the leaving group.
