Identify 'B' in the following reaction Ethyl cyanide H ₂ O A H ₂ O / dil HCl B + NH ₃
Options
- AEthanoic acid
- BEthanamide
- CPropanoic acid
- DPropanamide
Correct 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
