Observe the following molecules :
`PCl_(5) , BrF_(5), ClF_(5), PF_(5)ClF_(3), XeF_(4), XeF_(2), IF_(5)` The number of molecules having square pyramidal geometry from the above is

Options

A. 4
B. 5
C. 3
D. 6

Answer

C

Explanation

The number of molecules having square pyramidal geometry from the given molecules is 3, i.e., `BeF_(5), IF_5), CIF_(5)` . The geometries of the other given molecules are as follows :
`{:("Molecules"," Geometry (shape)"),(PCI_(5),"Trigonal bipyramidal"),(PF_(5),"Trigonal bipyramidal"),(CIF_(3),"T-shaped"),(XeF_(4),"Square planer"),(XeF_(2),"Linear"):}`
