Vedclass · Answer

(C) The solubility of alkaline earth metal fluorides is governed by the balance between lattice energy and hydration energy. $BeF_2$ is highly soluble in water due to the very high hydration energy of the small $Be^{2+}$ ion,which compensates for its lattice energy. As the size of the cation increases from $Be^{2+}$ to $Ba^{2+}$,the hydration energy decreases significantly,leading to a decrease in solubility. Therefore,the correct order is $MgF_2 < CaF_2 < SrF_2 < BeF_2$.
