Observe the following molecules. PCl 5 , BrF 5 , ClF 5 , PF 5 , ClF 3 , XeF 4 , XeF 2 , IF 5 The number of…

The following number of molecules having square pyramidal geometry from the above is ${\mathrm{BrF}}_5,{\mathrm{ClF}}_5,{\mathrm{IF}}_5$. All are ${\mathrm{sp}}^3{\mathrm{d}}_2$hybridised and undergoes square pyramidal geometry. In case of ${\mathrm{BrF}}_5,$ electron pair is $6$. Hence, the geometry ground the central atom is square pyramidal.
