    Which of the following alkaline earth metal sulphates has hydration enthalpy higher than the lattice enthalpy?

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

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

    C) \[~BeS{{O}_{4}}\]

    D) \[~BaS{{O}_{4}}\]

    Correct Answer: C

    Solution :

     Hydration energy decreases down the group, whereas lattice energy remains almost constant. Thus, hydration enthalpy is higher than the lattice enthalpy in case of \[\text{BeS}{{\text{O}}_{\text{4}}}\text{.}\]
