    Arrange the following in the increasing order of their bond order                 \[O2,\,\,O_{2}^{+},\,\,O_{2}^{-}\]and\[O_{2}^{2-}\]

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

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

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

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

    Correct Answer: A

    Solution :

    Species:               \[O_{2}^{2-}\]   \[O_{2}^{-}\]     \[{{O}_{2}}\]      \[O_{2}^{+}\] Bond order:          \[1\]    \[1.5\]  \[2\]     \[2.5\]
