Vedclass · Answer

(A) To determine the hybridization,we use the formula: $	ext{Steric Number} = \frac{1}{2} (V + M - C + A)$,where $V$ is the number of valence electrons of the central atom,$M$ is the number of monovalent atoms,$C$ is the cationic charge,and $A$ is the anionic charge.$(A)$ $ICl_4^-$: $	ext{Steric Number} = \frac{1}{2} (7 + 4 + 1) = 6$. Hybridization is $sp^3d^2$ $(R)$.$(B)$ $NO_3^-$: $	ext{Steric Number} = \frac{1}{2} (5 + 0 + 1) = 3$. Hybridization is $sp^2$ $(S)$.$(C)$ $PCl_4^+$: $	ext{Steric Number} = \frac{1}{2} (5 + 4 - 1) = 4$. Hybridization is $sp^3$ $(P)$.$(D)$ $SiF_6^{2-}$: $	ext{Steric Number} = \frac{1}{2} (4 + 6 + 2) = 6$. Hybridization is $sp^3d^2$ $(R)$.Thus,the correct matching is $A-R, B-S, C-P, D-R$.
