    In which reaction, there is change in oxidation number of N

    A)  \[2N{{O}_{2}}\to {{N}_{2}}{{O}_{4}}\]

    B)  \[N{{H}_{4}}OH\to N{{H}_{4}}^{+}+O{{H}^{-}}\]

    C)  \[{{N}_{2}}{{O}_{5}}+{{H}_{2}}O\to 2HN{{O}_{3}}\]

    D)  \[2N{{O}_{2}}+{{H}_{2}}O\to HN{{O}_{3}}+HN{{O}_{2}}\]

    Correct Answer: D

    Solution :

     In reaction [d] oxidation number changes from \[+4\] in \[N{{O}_{2}}\] to \[+3\] in \[HN{{O}_{2}}\] and \[+\sin HN{{O}_{3}}\]
