    \[{{N}_{2}}\] and \[{{O}_{2}}\] are converted into monoanions \[N_{2}^{-}\] and \[O_{2}^{-}\] respectively, which of the following statements is wrong [CBSE PMT 1997]

    A)                 In \[{{N}_{2}},\] the \[N-N\] bond weakens

    B)                 In \[{{O}_{2}},\] the \[O-O\] bond order increases

    C)                 In\[{{O}_{2}},\] bond length increases

    D)                 \[N_{2}^{-}\] becomes diamagnetic

    Correct Answer: B

    Solution :

                    In the conversion of \[{{O}_{2}}\] into \[O_{2}^{-}\] bond order decreases.
