$HgCl_2$

Vedclass · Answer

(B) $HgCl_2$ (mercury$(II)$ chloride) is a covalent compound with a low melting point $(276 \ ^\circ C)$ and a boiling point of $302 \ ^\circ C$. Due to its covalent nature and weak intermolecular forces,it easily volatilises upon heating. In contrast,$MgCl_2$,$CaCl_2$,and $FeCl_3$ are primarily ionic in nature and have significantly higher melting and boiling points.
