MCQ
The correct $\text{IUPAC}$ name of $\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right]$ is:
  • ✓
    Diamminedichloridoplatinum $(II).$
  • B
    Diamminedichloridoplatinum $(IV).$
  • C
    Diamminedichloridoplatinum $(0).$
  • D
    Dichloridodiammineplatinum $(IV).$
✓

Answer

Correct option: A.
Diamminedichloridoplatinum $(II).$
The complex compound is $\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right]. NH_3$ is a neutral ligand and named as amine$. Cl$ is anion ligand and named as chloride. Di or tri is prefixed to represent the number. So the name of the compound is$-$ Diamminedichloridoplatinum $(II).$
$(II)$ represent the oxidation state of platinum.
