    Which one of the following is not a base?

    A)  \[{{\text{N}}_{\text{2}}}{{\text{H}}_{\text{4}}}\]                            

    B)  \[\text{N}{{\text{H}}_{\text{2}}}\text{OH}\]

    C)  \[{{\text{(C}{{\text{H}}_{3}}\text{)}}_{3}}N\]                   

    D)  \[H{{N}_{3}}\]

    Correct Answer: D

    Solution :

                     Hydrazoic acid \[\text{(}{{\text{N}}_{3}}\text{H)}\] is an important hydride of nitrogen but unlike ammonia and hydrazine, it is acidic in nature. Acidic nature of \[{{\text{N}}_{\text{3}}}\text{H}\] is also confirmed by the reaction of \[{{\text{N}}_{\text{3}}}\text{H}\] with Mg as- \[2{{N}_{3}}H+Mg\,\xrightarrow{{}}\underset{\text{Magnesium}\,\text{azide}}{\mathop{Mg{{({{N}_{3}})}_{2}}}}\,+{{H}_{2}}\]
