    The bond order in the species \[{{O}_{2}},O_{2}^{+}\] and \[O_{2}^{-}\]follows the order

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

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

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

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

    Correct Answer: B

    Solution :

    Bond order \[{{O}_{2}}=2\] Bond order of \[O_{2}^{+}=2.5\] Bond order of \[O_{2}^{-}=1.5\] Hence, the order of bond order is as                         \[O_{2}^{+}>{{O}_{2}}>O_{2}^{-}.\]
