    Which one of the following alkaline earth metal sulphates has its hydration enthalpy greater than its lattice enthalpy ? [JEE Main Solved Paper-2015 ]

    A) \[BaS{{O}_{4}}\]                              

    B) \[SrS{{O}_{4}}\]

    C) \[CaS{{O}_{4}}\]                              

    D) \[BeS{{O}_{4}}\]

    Correct Answer: D

    Solution :

    \[BeS{{O}_{4}}\]\[B{{e}^{2+}}\]hydration energy is greater than lattice energy due to its covalent nature and hence more soluble in water.
