Solution

## Step 1: Hybridization:“Hybridization is defined as the process of intermixing of the orbitals of slightly different energies so as to redistribute their energies, resulting in the formation of a new set of orbitals of equivalent energies and shape.”Step 2: Formula used for calculation: $\mathrm{Steric}\mathrm{number}=\frac{1}{2}\left[\mathrm{V}+\mathrm{M}-\mathrm{C}+\mathrm{A}\right]$Where V is the number of valence electrons, M is the monovalent electron, C is the positive charge and A represents the negative charge.Step 3: Calculation for Hybridisation of ${\mathrm{ClF}}_{5}$:The total number of valence electrons of chlorine in ${\mathrm{ClF}}_{5}$ is 7 and there are 5 monovalent atoms.$\mathrm{Steric}\mathrm{number}=\frac{1}{2}\left[7+5\right]\phantom{\rule{0ex}{0ex}}\mathrm{Steric}\mathrm{number}=\frac{1}{2}×12=6$The Steric number is 6, thus the hybridization of ${\mathrm{ClF}}_{5}$ is ${\mathrm{sp}}^{3}{\mathrm{d}}^{2}$.Step 4: Shape of ${\mathrm{ClF}}_{5}$:As per VSEPR, the shape for ${\mathrm{sp}}^{3}{\mathrm{d}}^{2}$ hybridization is square pyramidal with asymmetric charge distribution around the central atom.The structure of ${\mathrm{ClF}}_{5}$is given below: Thus, the shape of ${\mathrm{ClF}}_{5}$ is square pyramidal.
