$SF_6$

Vedclass · Answer

(C) To determine the geometry,we calculate the hybridization of the central atom:$1$. For $SF_6$,the central atom is $S$ (Sulfur). It has $6$ valence electrons and forms $6$ bonds with $F$ atoms. The steric number is $6 + 0 = 6$,which corresponds to $sp^3d^2$ hybridization and an octahedral geometry.$2$. $TeF_4$ has a steric number of $5$ ($4$ bond pairs + $1$ lone pair),resulting in a see-saw shape.$3$. $SeCl_2$ has a steric number of $4$ ($2$ bond pairs + $2$ lone pairs),resulting in a bent shape.$4$. $SeF_4$ has a steric number of $5$ ($4$ bond pairs + $1$ lone pair),resulting in a see-saw shape.Therefore,$SF_6$ is the only octahedral molecule among the given options.
