Ethanamide [1] hydrolyzes in a sulfuric medium to form ethanoic acid [2].
The reaction mechanism occurs in the following steps:
Stage 1. Protonation of carbonyl oxygen.
Stage 2. Nucleophilic attack of water on carbonyl carbon
Stage 3. Deprotonation of water and protonation of the amino group.
Stage 4. ammonia removal
Stage 5. deprotonation of carbonyl oxygen
