Identify ' B ' in the following sequence of reactions. Acetic acid [ ] Thionyl chloride A Ammonia B

Options

  1. AEthyl amine
  2. BAmmonium acetate
  3. CAcetyl chloride
  4. DAcetamide

Correct answer

D. Acetamide

Step-by-step solution

Acetic acid undergoes reaction with thionyl chloride to form acetyl chloride: CH₃COOH + SOCl₂ CH₃COCl + SO₂ + HCl Acetyl chloride then reacts with ammonia via nucleophilic acyl substitution to form acetamide: CH₃COCl + 2NH₃ CH₃CONH₂ + NH₄Cl The sequence produces acetamide, which corresponds to option D. Final answer: D
