    The reagent that reacts with nitromethane to form methyl hydroxylamine is:

    A)  \[Zn/HCl\]         

    B)  \[Zn/N{{H}_{4}}Cl\]

    C)  \[Zn/NaOH\]   

    D) \[Sn/HCl\]

    Correct Answer: B

    Solution :

                    Nitromethane forms methyl hydroxylamine on reduction in neutral medium with\[Zn/N{{H}_{4}}Cl\]. \[\underset{nitromethane}{\mathop{C{{H}_{3}}N{{O}_{2}}}}\,+4[H]\xrightarrow[\Delta ]{Zn/N{{H}_{4}}Cl}\] \[\underset{\begin{smallmatrix}  N-N-methyl\text{ }hydroxyl \\  \,\,\,\,\,\,\,\,\,\,\,\,\,\,amine \end{smallmatrix}}{\mathop{C{{H}_{3}}NHOH}}\,+{{H}_{2}}O\]
