    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 :

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