The hybridization of tin in ${\mathrm{SnCl}}_2$ is ${\mathrm{sp}}^2$ and it has one lone pair and two bond pairs. Hence, geometry should be Bent shape.

The hybridisation of xenon in ${\mathrm{XeF}}_4$ is ${\mathrm{sp}}^3{\mathrm{d}}^2$ and it has two lone pairs and four bond pairs. Hence, geometry should be square planar.

The hybridisation of chlorine in ${\mathrm{ClF}}_3$ is ${\mathrm{sp}}^3\mathrm{d}$ and it has three lone pairs and three bond pairs. Hence, geometry should be T-shape.

The hybridisation of Iodine in ${\mathrm{IF}}_5$ is ${\mathrm{sp}}^3{\mathrm{d}}^2$ and it has one lone pair and five bond pairs. Hence, geometry should be square pyramidal.
