Question:

The group of molecules having identical shape is: BF3, PCl3, XeO3, SF4, XeF4, CCl4, CIF3, XeOF2, XeF+3, PCl5, IF5, XeO2F2

CIF3,XeOF2,XeF+3

SF4,XeF4,CCI4

PCl5,IF5,XeO2F2

BF3,PCl3,XeO3

Solution:

The group of molecules having identical shape is CIF3, XeOF2, XeF+3. In these molecules, the central atom has 2 lone pairs of electrons and 3 bonding domains. The electron geometry is trigonal bipyramidal geometry and the molecules are T shaped.
