Among I 3 + , SiO 4 4 - , SO 2 Cl 2 , XeF 2 , SF 4 , ClF 3 , Ni CO 4 , XeO 2 F 2 , PtCl 4 2 - , XeF 4 , and SOCl 2 , the total number of species having sp 3 hybridised central atom is

Step-by-step solution

I 3 + ion has sp 3 hybridisation and bent shape containing two bond pairs and two lone pairs. Structure of SiO 4 4 − is tetrahedral structure and Si is sp 3 hybridised. The molecular geometry of SOCl 2 is trigonal pyramidal and its electron geometry is tetrahedral. In this molecule sulphur undergo sp 3 hbridisation, XeF 2 molecule is linear molecule but it is sp 3 d hybridised. In SF 4 , sulphur undergo sp 3 d hybridisation and molecule has see-saw shape. In ClF 3 , chlorine undergo sp 3 d hybridisation and s
