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
