    Oxidation number of nitrogen is highest in

    A) \[{{N}_{3}}H\]

    B)  \[{{N}_{2}}{{O}_{4}}\]

    C)  \[N{{H}_{2}}OH\]

    D) \[N{{H}_{3}}\]

    Correct Answer: B

    Solution :

     In\[{{\text{N}}_{\text{3}}}\text{H:}\] Oxidation number of \[N=-\frac{1}{3}\] In \[{{N}_{2}}{{O}_{4}}:\] Oxidation number of\[\text{N = + 4}\]  In \[\text{N}{{\text{H}}_{\text{2}}}\text{OH:}\] Oxidation number of \[N=-1\] In\[~N{{H}_{3}}:\] Oxidation number of \[N=-\text{ }3\] Hence, in\[{{\text{N}}_{\text{2}}}{{\text{O}}_{\text{4}}}\]the oxidation number of nitrogen is highest.
