$BeF_2$

Vedclass · Answer

(D) $BeF_2$ is predominantly covalent in nature due to the small size and high polarizing power of the $Be^{2+}$ ion. Because of its covalent character,it has a significantly lower melting point compared to the other alkaline earth metal fluorides,which are primarily ionic. $BeF_2$ melts at approximately $800 \, ^\circ C$,whereas other alkaline earth metal fluorides like $CaF_2$,$SrF_2$,and $BaF_2$ have much higher melting points (typically above $1200 \, ^\circ C$).
