    In the following reaction\[C{{H}_{3}}CHO+N{{H}_{2}}.N{{H}_{2}}\xrightarrow{{}}A\]                                                 \[{{\mu }_{p}}\] Identify A and B.

    A) \[{{\mu }_{i}}\]

    B) \[{{n}_{i}}\sqrt{\frac{{{\mu }_{n}}}{{{\mu }_{p}}}}\]

    C) \[{{n}_{h}}\sqrt{\frac{{{\mu }_{n}}}{{{\mu }_{p}}}}\]

    D) \[{{n}_{i}}\sqrt{\frac{{{\mu }_{p}}}{{{\mu }_{n}}}}\]

    Correct Answer: A

    Solution :

    Aldehydes can be reduced to alkanes with hydrazine and\[{{C}_{2}}{{H}_{5}}ONa\] at\[150-200{}^\circ C\]. This reaction is known as Wolf-Kishner reduction. \[\text{C}{{\text{H}}_{\text{3}}}\text{CHO}+\text{N}{{\text{H}}_{\text{2}}}\text{.N}{{\text{N}}_{\text{3}}}\xrightarrow{{}}\text{C}{{\text{H}}_{\text{3}}}\text{CH =NN}{{\text{H}}_{\text{2}}}\]
