Identify product ' B ' in the following sequence of reaction Aniline [273 ~K ] NaNo ₂+ HCl A [ ] H ₂ O B + N ₂

Options

  1. ASodium phenoxide
  2. BNitrobenzene
  3. CBenzenediazonium chloride
  4. DPhenol

Correct answer

D. Phenol

Step-by-step solution

Aniline undergoes diazotization with sodium nitrite and hydrochloric acid at 273 K, forming benzenediazonium chloride as product A : C₆ H₅ NH₂ + NaNO₂ + 2HCl [273 K] C₆ H₅ N₂ + Cl- + NaCl + 2H₂ O Product A is then hydrolyzed in water with heating, replacing the diazonium group with a hydroxyl group: C₆ H₅ N₂ + Cl- + H₂ O [ ] C₆ H₅ OH + N2 ^ + HCl This yields phenol as product B , corresponding to option D.
