Vedclass · Answer

(D) To determine the number of valence electrons around the central atom,we calculate the total electrons in the valence shell including bonding and lone pairs.$1$. In $BF_4^{-}$,the central $B$ atom forms $4$ single bonds with $F$ atoms,resulting in $4 	imes 2 = 8$ electrons.$2$. In $NCl_3$,the central $N$ atom has $3$ bond pairs and $1$ lone pair,totaling $8$ electrons.$3$. In $PCl_4^{+}$,the central $P$ atom forms $4$ single bonds with $Cl$ atoms,resulting in $4 	imes 2 = 8$ electrons.$4$. In $SF_4$,the central $S$ atom has $4$ bond pairs and $1$ lone pair,totaling $10$ electrons $(4 	imes 2 + 2 = 10)$.Thus,$SF_4$ does not follow the octet rule as it has $10$ valence electrons.

In which of the following species is the central atom not surrounded by exactly $8$ valence electrons?
