Vedclass · Answer

(B) The number of orbitals involved in hybridization $(H)$ is calculated as $H = \frac{1}{2} [V + M - C + A]$,where $V$ is the number of valence electrons of the central atom,$M$ is the number of monovalent atoms,$C$ is the charge of the cation,and $A$ is the charge of the anion.For $[XeF_3]^+$,$H = \frac{1}{2} [8 + 3 - 1] = 5$,which corresponds to $sp^3d$ hybridization with $2$ lone pairs. This results in a $T$-shaped geometry.For $[XeF_5]^+$,$H = \frac{1}{2} [8 + 5 - 1] = 6$,which corresponds to $sp^3d^2$ hybridization with $1$ lone pair. This results in a square pyramidal geometry.Therefore,the correct option is $B$.

$SbF_5$ reacts with $XeF_4$ and $XeF_6$ to form ionic compounds $[XeF_3]^+ [SbF_6]^-$ and $[XeF_5]^+ [SbF_6]^-$ respectively. What are the molecular shapes of the $[XeF_3]^+$ and $[XeF_5]^+$ ions,respectively?
