    Stability of the species\[L{{i}_{2}},Li_{2}^{-}\]and\[Li_{2}^{+}\]increases in the order of :     AIEEE Solevd Paper-2013

    A) \[L{{i}_{2}}<Li_{2}^{+}<Li_{2}^{-}\]         

    B) \[Li_{2}^{-}<Li_{2}^{+}<L{{i}_{2}}\]         

    C) \[L{{i}_{2}}<Li_{2}^{-}<Li_{2}^{+}\]         

    D) \[Li_{2}^{-}<L{{i}_{2}}<Li_{2}^{+}\]

    Correct Answer: B

    Solution :

    B.O. of\[Li_{2}^{+}=0.5\] B.O. of \[Li_{2}^{-}=0.5\] Hence stability order\[=Li_{2}^{-}<Li_{2}^{+}<L{{i}_{2}}\]
