JEE Main levelSingle correct optionDifficulty 2 of 3nc174

Nitrobenzene is reduced with and aqueous (neutral medium). The main product is

  1. Aaniline
  2. BN-phenylhydroxylamine,
  3. Cazoxybenzene
  4. D4-aminophenol

Answer: B

In neutral medium (Zn/NH4Cl) the reduction stops at the hydroxylamine stage. Aniline needs acidic metal reduction, azoxybenzene needs alkaline medium and 4-aminophenol forms on electrolytic reduction in strong acid.
