Question

The correct IUPAC name of \([ \text{Pt}(\text{NH}_3)_2\text{Cl}_2 ]^{2+} \) is:

• A. Diamminedichloridoplatinum (II)
• B. Diamminedichloridoplatinum (IV)
• C. Diamminedichloridoplatinum (O)
• D. Diamminedichloridoplatinate (IV)

Hint:

When naming coordination compounds, ensure the oxidation state of the metal and the ligands are correctly identified.

Answer 1

The Correct Option is C

Step 1: Understanding the IUPAC name. In this compound, platinum is in the +2 oxidation state, and the ligands are ammonia (NH_3) and chloride (Cl^-). The correct IUPAC name is based on the oxidation state of the platinum ion and the ligands attached to it. 

Step 2: Conclusion. Thus, the correct IUPAC name is Diamminedichloridoplatinum (II), corresponding to option (A).
