    Of the following acids the one which has the capability to form complex compound and also possesses oxidising and reducing properties is

    A)  \[HN{{O}_{3}}\]                              

    B)  \[HN{{O}_{2}}\]

    C)  \[HCOOH\]                       

    D)  \[HCN\]

    Correct Answer: B

    Solution :

                     Among the given options, only \[\text{HN}{{\text{O}}_{\text{2}}}\]acts as oxidising and reducing agent. This is because in \[\text{HN}{{\text{O}}_{\text{2}}},N\]is present in +3 oxidation state, so it can be oxidised (ie, act as reducing agent) to higher oxidation state or reduced (ie, act as oxidising agent) to lower oxidation state. It also possess complex forming ability.
