Vedclass · Answer

(D) The octet rule,proposed by Lewis,states that atoms tend to bond such that they have $8$ electrons in their valence shell,achieving a stable noble gas configuration.In $SF_6$,the central $S$ atom has $12$ valence electrons.In $PCl_5$,the central $P$ atom has $10$ valence electrons.In $XeF_2$,the central $Xe$ atom has $10$ valence electrons.Since these central atoms do not have $8$ electrons,they are examples of an expanded octet and do not obey the octet rule.

The set of molecules in which the central atom does not obey the octet rule is
