The shape/structure of ${\left[{\mathrm{XeF}}_5\right]}^{-}$and ${\mathrm{XeO}}_3{\mathrm{ }\mathrm{F}}_2$, respectively, are:

Given data:

The shape/structure of ${\left[{\mathrm{XeF}}_5\right]}^{-}$and ${\mathrm{XeO}}_3{\mathrm{ }\mathrm{F}}_2$ are asked to be specified here.

Formula/concept: Noble gases

Detailed solution:

${\left[{\mathrm{XeF}}_5\right]}^{-}$has 5 bond pairs and 2 lone pairs present in it. It forms a $s{p}^3{d}^3$ hybridization and the structure is pentagonal planar.

In case of ${\mathrm{XeO}}_3{F}_2$ it has 5 bond pairs and 0 lone pairs. It forms a $s{p}^{3}d$ hybridization and the structure is trigonal bipyramidal.

Therefore, option (B) is correct.
