    Hydrogen has an ionisation energy of \[1311\text{ }kJ\text{ }mo{{l}^{-1}}\]  and for chlorine it is \[1256\text{ }kJ\text{ }mo{{l}^{-1}}.\] Hydrogen forms \[{{H}^{+}}\left( aq \right)\] ions but chlorine does not form \[C{{l}^{+}}(aq)\] ions because

    A) \[{{H}^{+}}\] has lower hydration enthalpy

    B) \[C{{l}^{+}}\]has lower hydration enthalpy

    C) \[Cl\] has high electron affinity

    D) \[Cl\] has high electronegativity

    Correct Answer: B

    Solution :

    [b] Hydration energy of \[C{{l}^{+}}\] is very less than \[{{H}^{+}}\]hence it doesn't form \[C{{l}^{+}}\] (aq) ion.
