    According to bond order concept, the correct order of stability of\[{{O}_{2}},O_{2}^{+}\]and\[O_{2}^{-}\]is:

    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: D

    Solution :

                    Bond order oc stability Species                Bond order \[O_{2}^{+}\]                    2.5 \[{{O}_{2}}\]                      2.0 \[O_{2}^{-}\]                     1.5 Hence, the order of stability is:                 \[O_{2}^{+}>{{O}_{2}}>O_{2}^{-}\]
