Question

The correct IUPAC name of $[P t (N H_{3})_{2} C l_{2}]$ is
(a) Diamminedichloridoplatinum (II)
(b) Diamminedichloridoplatinum (IV)
(c) Diamminedichloridoplatinum (0)
(d) Dichloridodiammineplatinum (IV)

Solution

The complex compound is $[P t (N H_{3})_{2} C l_{2}] .$
the ligands present in the compound are
(i) $N H_{3}$ neutral ligand represented as an amine.
(ii) Cl- anion ligand (ending with -O-). represented as chlorido and di prefixed to represent two ligands.
The oxidation number of platinum in the compound is 2. Hence, correct IUPAC name of $[P t (N H_{3})_{2} C l_{2}]$ is
Diammine dichloridoplatinum (II)
So, the option (a) is correct.
