Vedclass · Answer

(D) To determine the number of lone pairs on the central atom,we calculate the valence electrons and subtract the electrons involved in bonding:$1$. In $[ClO_3]^-$,the central $Cl$ atom has $7$ valence electrons + $1$ (negative charge) = $8$. It forms $3$ double bonds with $O$ atoms ($6$ electrons used). Lone pairs = $(8-6)/2 = 1$.$2$. In $XeF_4$,the central $Xe$ atom has $8$ valence electrons. It forms $4$ single bonds with $F$ atoms ($4$ electrons used). Lone pairs = $(8-4)/2 = 2$.$3$. In $SF_4$,the central $S$ atom has $6$ valence electrons. It forms $4$ single bonds with $F$ atoms ($4$ electrons used). Lone pairs = $(6-4)/2 = 1$.$4$. In $[I_3]^-$,the central $I$ atom has $7$ valence electrons + $1$ (negative charge) = $8$. It forms $2$ single bonds with $I$ atoms ($2$ electrons used). Lone pairs = $(8-2)/2 = 3$.Thus,$[I_3]^-$ has the maximum number of lone pairs $(3)$. The correct option is $(D)$.
