Question

Which reagent converts nitrobenzene to N-phenyl hydroxylamine?

• A. Zn/HCl
• B. H₂O₂
• C. Zn/NH₄Cl
• D. LiAlH₄

Hint:

Mild reducing agents give partial reduction products in nitro compounds.

Answer 1

The Correct Option is C

Step 1: Partial reduction of nitrobenzene gives N-phenyl hydroxylamine. Step 2: \beginitemize • Zn/HCl and LiAlH₄ reduce nitrobenzene fully to aniline. • Zn/NH₄Cl gives controlled reduction to hydroxylamine. \enditemize Hence, correct reagent is Zn/NH₄Cl.
