Vedclass · Answer

(C) Hypervalent compounds are those in which the central atom has more than $8$ electrons in its valence shell (expanded octet).In $PCl_5$,the central phosphorus atom $(P)$ is bonded to $5$ chlorine atoms,resulting in $5 	imes 2 = 10$ electrons in its valence shell.Since $10 > 8$,$PCl_5$ is a hypervalent compound.In contrast,$NO_3^-$ follows the octet rule,$BF_3$ is hypovalent ($6$ electrons),and $CH_4$ follows the octet rule ($8$ electrons).

Which one of the following compounds is hypervalent?
