Vedclass · Answer

(D) Hydration energy is inversely proportional to the ionic size of the cation. As the size of the cation decreases,the charge density increases,leading to stronger interaction with water molecules. The ionic radii of the given alkaline earth metal ions follow the order: $Mg^{2+} Therefore,$Mg^{2+}$ has the smallest size and the highest charge density,resulting in the maximum hydration energy.
