Amides hydrolyze in acidic media, under heating, forming amines and carboxylic acids.



Ethanamide hydrolyzes in a sulfuric medium to form ethanoic acid .
The reaction mechanism occurs in the following steps:

Stage 1. Protonation of carbonyl oxygen.



Stage 2. Nucleophilic attack of water on the carbonyl carbon



Stage 3. Deprotonation of water and protonation of the amino group.



Stage 4. Elimination of ammonia



Step 5. Deprotonation of carbonyl oxygen
