    Which ionisation potential \[\left( IP \right)\] in the following equations involves the greatest amount of energy [Pune CET 1998]

    A) \[Na\to N{{a}^{+}}+{{e}^{-}}\]

    B) \[{{K}^{+}}\to {{K}^{2+}}+{{e}^{-}}\]

    C) \[{{C}^{2+}}\to {{C}^{3+}}+{{e}^{-}}\]

    D) \[C{{a}^{+}}\to C{{a}^{2+}}+{{e}^{-}}\]

    Correct Answer: B

    Solution :

    \[{{K}^{+}}\to {{K}^{2+}}+{{e}^{-}}\]. Since \[{{e}^{-}}\] is to be removed from stable configuration.
