Options
- A. Ethanoic acid
- B. Ethanamide
- C. Propanoic acid
- D. Propanamide
Answer
C. Propanoic acid
Step-by-step solution
Ethyl cyanide is CH _3 CH _2 CN . Partial hydrolysis of ethyl cyanide yields propanamide (A). CH _3 CH _2 CN H _2 O CH _3 CH _2 CONH _2 Complete hydrolysis of propanamide in the presence of dilute HCl yields propanoic acid (B) and ammonia. CH _3 CH _2 CONH _2 H _2 O / dil HCl CH _3 CH _2 COOH + NH _3 Therefore, B is propanoic acid. Answer: Propanoic acid
