Solution:
Molecule
No. of bond angles
No. of lone pairs
Hybridisa-tion
Shape
$SF_{4}$
4
1
$sp^{3}d$
Irregular tetrahedral
$CF_4$
4
$-$
$sp^{3}$
tetrahedral
$XeF_4$
4
2
$sp^{3}d^{2}$
square planar
| Molecule | No. of bond angles | No. of lone pairs | Hybridisa-tion | Shape |
|---|---|---|---|---|
| $SF_{4}$ | 4 | 1 | $sp^{3}d$ | Irregular tetrahedral |
| $CF_4$ | 4 | $-$ | $sp^{3}$ | tetrahedral |
| $XeF_4$ | 4 | 2 | $sp^{3}d^{2}$ | square planar |
