Reduction of nitrobenzene in the presence of Zn/NH4Cl gives:
Correct answer: D. N-phenyl hydroxyl amine
- A. hydrazobenzene
- B. aniline
- C. azobenzene
- D. N-phenyl hydroxyl amine
Explanation
The reduction of nitrobenzene in the presence of Zn/NH4Cl gives N-phenylhydroxylamine as the product. Here's an outline of the mechanism for this reaction:1. The nitrobenzene is protonated by the ammonium chloride to form a nitrobenzenium ion.2. Zinc metal reduces the nitrobenzenium ion to a nitrosobenzene intermediate by donating electrons to the nitro group.3. The nitrosobenzene intermediate is then protonated by the ammonium chloride to form a nitrosobenzenium ion.4. Zinc metal reduces the nitrosobenzenium ion to N-phenylhydroxylamine by donating electrons to the nitroso group.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
