Which one of the following alkaline earth metal sulphates has its hydration enthalpy greater than its lattice enthalpy?

A

`BaSO_(4)`

B

`SrSO_(4)`

C

`CaSO_(4)`

D

`BeSO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
D
Covalent character increases, when the cation has small size and high charge density.
Among all these, `Mg^(2(+))` size is smallest so `MgCl`, tends to be more covalent in nature.
