(a)
Interpretation:
A mechanism corresponding to the hydrolysis of
Concept introduction:
The basic hydrolysis of an amide comprises of three steps. The first step is the addition of the nucleophile. The second step is the elimination of the leaving group. The third step is the proton transfer.
(b)
Interpretation:
A mechanism corresponding to the hydrolysis of
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.

- Using what we have learned in CHEM 2310 and up through class on 1/31, propose a series of reaction steps to achieve the transformation below. Be sure to show all reagents and intermediates for full credit. You do not need to draw mechanism arrows, but you do need to include charges where appropriate. If you do not put your group name, you will get half credit at most. ?
