    Reduction of nitrobenzene in the presence of \[\text{Zn/N}{{\text{H}}_{\text{4}}}\text{Cl}\]gives:

    A)  azo benzene

    B)  aniline

    C)   N-phenyl hydroxyl amine

    D)  hydrazobenzene

    Correct Answer: C

    Solution :

                     Reduction of nitrobenzene in neutral medium: \[Zn/N{{H}_{4}}Cl\] or \[Zn/CaC{{l}_{2}}\]reduce a nitro compound to hydroxyl amine. \[{{C}_{6}}{{H}_{5}}N{{O}_{2}}+2Zn+4N{{H}_{4}}Cl\xrightarrow{{}}\] \[\underset{\text{Phenyl}\,\text{hydroxyl}\,\text{amine}}{\mathop{{{C}_{6}}{{H}_{5}}NHOH}}\,+2ZnC{{l}_{2}}+{{H}_{2}}O+4N{{H}_{3}}\] Phenyl hydroxyl amine
