    Decreasing order of stability of \[{{O}_{2}},O_{2}^{-},O_{2}^{+}\] and \[O_{2}^{2-}\]is

    A)  \[O_{2}^{+}>{{O}_{2}}>O_{2}^{-}>O_{2}^{2-}\]               

    B) \[O_{2}^{2-}>O_{2}^{-}>{{O}_{2}}>O_{2}^{+}\]

    C)         \[{{O}_{2}}>O_{2}^{+}>O_{2}^{2-}>O_{2}^{-}\]

    D)         \[O_{2}^{-}>O_{2}^{2-}>O_{2}^{+}>{{O}_{2}}\]

    Correct Answer: A

    Solution :

    Order of stability \[\propto \] bond order \[\therefore \]Order of the stability of given specie \[O_{2}^{+}>{{O}_{2}}>O_{2}^{-}>O_{2}^{2-}\] Bond order .2.5      2      1.5    1
