Vedclass · Answer

(C) For $XeF_4$: The central atom $Xe$ has $8$ valence electrons. It forms $4$ bonds with $F$ atoms and has $2$ lone pairs. The steric number is $6$ ($sp^3d^2$ hybridization),resulting in a square planar geometry.For $XeF_5^-$: The central atom $Xe$ has $8$ valence electrons,plus $1$ from the negative charge,forming $5$ bonds with $F$ atoms and having $2$ lone pairs. The steric number is $7$ ($sp^3d^3$ hybridization),resulting in a pentagonal planar geometry.For $SnCl_2$: The central atom $Sn$ has $4$ valence electrons. It forms $2$ bonds with $Cl$ atoms and has $1$ lone pair. The steric number is $3$ ($sp^2$ hybridization),resulting in an angular or bent shape.
