Verified Answer
Molecular shapes of SF4, CF4 and XeF4 are (2000S)a)the same, with 2, 0...
The structure of species can be predicted on the basis of hybridisation which in turn can be known by knowing the number of hybrid orbitals (H) in that species

For SF4 : S is sp3d hybridised in SF4.
Thus SF4 has 5 hybrid orbitals of which only four are used by F, leaving one lone pair of electrons on sulphur.
For CF4 :
  ∴ sp3 hybridisaion
Since all the four orbitals of carbon are involved in bond formation, no lone pair is present on C having four valence electrons
For XeF4 :
 ∴ sp3d2 hybridization  of the six hybrid orbitals, four form bond with F, leaving behind two lone pairs of electrons on Xe.
