$BeF_2, BeF_2$

Vedclass · Answer

(C) $BeF_2$ is predominantly covalent in nature,which results in a significantly lower melting point $\left(800^{\circ} C\right)$ compared to other alkaline earth metal fluorides,which are ionic and melt at temperatures above $1200^{\circ} C$.Furthermore,$BeF_2$ is the most soluble fluoride in water among group $2$ elements because the high hydration energy of the small $Be^{2+}$ ion outweighs its lattice energy.

Among the fluorides of group $2$ elements,which is maximum soluble in water and has the minimum melting point,respectively?
