    Which of the following transitions involves maximum amount of energy [AIIMS 1992]

    A) \[{{M}^{-}}(g)\to M(g)\]

    B) \[M(g)\to {{M}^{+}}(g)\]

    C) \[{{M}^{+}}(g)\to {{M}^{2+}}(g)\]

    D) \[{{M}^{2+}}(g)\to {{M}^{3+}}(g)\]

    Correct Answer: D

    Solution :

    \[{{M}^{2+}}\to {{M}^{3+}}\] After the removal of \[2{{e}^{-}}\] the nuclear charge per \[{{e}^{-}}\] increases, due to which high energy is required to remove \[3{{e}^{-}}\].
