$BCl_3$

Vedclass · Answer

(D) $PCl_5$ acts as a chlorinating agent and reacts with many compounds to replace oxygen or increase the oxidation state of metals.$BCl_3$ is already a chloride of boron in its maximum oxidation state $(+3)$.Since boron cannot expand its oxidation state further and there is no oxygen to replace,$BCl_3$ does not react with $PCl_5$.In contrast,$Hg_2Cl_2$ can be oxidized to $HgCl_2$,$FeCl_2$ can be oxidized to $FeCl_3$,and $S_2Cl_2$ can react with $PCl_5$ to form $SCl_2$ or other sulfur chlorides.
