    Which of the following substances acts as an oxidising as well as a reducing agent?

    A) \[N{{a}_{2}}O\]\[\]              

    B) \[SnC{{l}_{2}}\]

    C) \[N{{a}_{2}}{{O}_{2}}\]                               

    D) \[NaN{{O}_{2}}\]

    Correct Answer: D

    Solution :

    [d] In \[N{{a}_{2}}O,SnC{{l}_{2}}\]and \[N{{a}_{2}}{{\text{O}}_{2}}\]central atom is either in lowest or highest oxidation state, so they can function either as an oxidizing .or a reducing agent but not both. However, the oxidation state of N in \[N{{a}_{2}}{{\text{O}}_{2}}\] is +3 which lies between its highest (+5) and lowest \[\left( -3 \right)\] values.
