Solution
The correct IUPAC name of [Pt(NH3)2Cl2]2+ is Diamminedichloridoplatinum (IV).
Explanation:
Diammine dichloridoplatinum (IV), where diammine indicates two neutral ammine (NH3) ligands and dichlorido indicates two chlorido (Cl−) ligands. Since ammine is neutral and each chlorido ligand carries −1 charge, the oxidation state of platinum is +4, giving the complex an overall charge of +2.
