Question number 9.50..

Dear Student,

The ​​IUPAC name for any of isomers with the molecular formula [ Pt(NH3)2Cl2]Cl2​
is diamminedichloroplatinum (IV) chloride.
NH3 and ClLigands are usually polar in nature and possess at least one unshared pair of valence electrons.
The total number of ligands  that get attached to the central metal atom in the coordination sphere is called the coordination number of the central metal atom. Here four ligands are attached to the Pt metal hence the co-ordiation number is = IV
Regards,
