Chemistry - CHEMICAL BONDING Question with Solution | TestHub

${\mathrm{SiF}}_4$ and ${\mathrm{SF}}_4$ are not isostructural because ${\mathrm{SiF}}_4$ is tetrahedral due to $s{p}^3$ hybridisation while ${\mathrm{SF}}_4$ has distorted tetrahedral geometry due to presence of lone pair.


Related Theory Two molecules are isostructural if they have a similar number of atoms arranged in a similar structure (spatial coordinates). Caution If they have same number of lone pair and bond pair, they are considered as isostructural.
