(D) To determine the molecular shapes and lone pairs ($L$.$P$.) on the central atoms:$1$. For $SF_4$: The central atom $S$ has $6$ valence electrons. It forms $4$ bonds with $F$ atoms,leaving $1$ lone pair. The shape is see-saw.$2$. For $CF_4$: The central atom $C$ has $4$ valence electrons. It forms $4$ bonds with $F$ atoms,leaving $0$ lone pairs. The shape is tetrahedral.$3$. For $XeF_4$: The central atom $Xe$ has $8$ valence electrons. It forms $4$ bonds with $F$ atoms,leaving $2$ lone pairs. The shape is square planar.Thus,the shapes are different with $1, 0$ and $2$ lone pairs of electrons on the central atoms,respectively.
