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

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

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

    Correct Answer: A

    Solution :

    Sol.         The bond order decreases in the order\[{{O}_{2}}^{+}(2.5)>{{O}_{2}}(2.0)>{{O}_{2}}^{-}(1.5)\].
