Based on VSEPR model, match the xenon compounds given in List-I with the corresponding geometries and the number of lone pairs on xenon given in List-II and choose the correct option.
  1. $\mathrm{P}-5, \mathrm{Q}-2, \mathrm{R}-3, \mathrm{~S}-1$
  2. $\mathrm{P}-5, \mathrm{Q}-3, \mathrm{R}-2, \mathrm{~S}-4$
  3. $\mathrm{P}-4, \mathrm{Q}-3, \mathrm{R}-2, \mathrm{~S}-1$
  4. $\mathrm{P}-4, \mathrm{Q}-2, \mathrm{R}-5, \mathrm{~S}-3$

Solution

$\mathrm{XeF}_2 \Rightarrow 2$ sigma bonds and 3 lone pairs on $\mathrm{Xe}$, number of hybrid orbitals $=5, \mathrm{sp}^3 \mathrm{~d}$ hybridisation geometry will be trigonal bipyramidal. $\mathbf{P}-\mathbf{5}$ $\mathrm{XeF}_4 \Rightarrow 4$ sigma bonds and 2 lone pairs on $\mathrm{Xe}$, number of hybrid orbitals $=6, \mathrm{sp}^3 \mathrm{~d}^2$ hybridisation , geometry will be octahedral. $\mathbf{Q}-\mathbf{3}$ $\mathrm{XeO}_3 \Rightarrow 3$ sigma bonds and 1 lone pairs on $\mathrm{Xe}$, number of hybrid orbitals $=4, \mathrm{sp}^3$ hybridisation , geometry will be tetrahedral. $\mathbf{R}-\mathbf{2}$ $\mathrm{XeO}_3 \mathrm{~F}_2 \Rightarrow 5$ sigma bonds and 0 lone pairs on $\mathrm{Xe}$, number of hybrid orbitals $=5, \mathrm{sp}^3 \mathrm{~d}$ hybridisation , geometry will be trigonal bipyramidal. $\mathbf{S}-\mathbf{4}$
