Vedclass · Answer

(D) $1$. $SiF_4$ has a tetrahedral geometry ($sp^3$ hybridization) where all $Si-F$ bond lengths are equal.$2$. $XeF_4$ has a square planar geometry ($sp^3d^2$ hybridization) with two lone pairs at axial positions,making all $Xe-F$ bond lengths equal.$3$. $BF_4^-$ has a tetrahedral geometry ($sp^3$ hybridization) where all $B-F$ bond lengths are equal.$4$. $SF_4$ has a see-saw geometry ($sp^3d$ hybridization) with one lone pair at an equatorial position. Due to the presence of the lone pair,the axial $S-F$ bonds and equatorial $S-F$ bonds have different bond lengths.
