Vedclass · Answer

(D) The $Be^{2+}$ cation has a very small size,which results in a very high hydration energy that significantly exceeds its lattice energy.Consequently,$BeF_2$ is highly soluble in water.In contrast,the fluorides of other alkaline earth metals have high lattice energies,making them relatively insoluble in water.The decreasing order of solubility for alkaline earth metal fluorides is $BeF_2 > MgF_2 > CaF_2 > SrF_2 > BaF_2$.
