Identify the product ' B ' in the following sequence of reactions. Ethanenitrile SnCl ₂, HCl A H ₃, O ⁺ B + NH ₄ Cl

Options

  1. AEthylamine
  2. BEthanamide
  3. CEthanol
  4. DEthanal

Correct answer

D. Ethanal

Step-by-step solution

Ethanenitrile undergoes Stephen reduction with SnCl ₂ and HCl to form ethanimine hydrochloride as product A: CH₃CN + SnCl ₂ + 2 HCl CH₃CH=NH HCl . Hydrolysis of A with H₃O^+ yields ethanal and ammonium chloride: CH₃CH=NH HCl + H₂O H₃O^+ CH₃CHO + NH₄Cl . Product B is ethanal ( CH₃CHO ), corresponding to option D. D
