The correct IUPAC name of \([ \text{Pt}(\text{NH}_3)_2\text{Cl}_2 ]^{2+} \) is:
Diamminedichloridoplatinate (IV)
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).
The Crystal Field Theory (CFT) of coordination compounds is based on the effect of different crystal fields (provided by the ligands taken as point charges) on the degeneracy of d-orbital energies of the central metal atom/ion. The splitting of the d-orbitals provides different electronic arrangements in strong and weak crystal fields. In tetrahedral coordination entity formation, the d-orbital splitting is smaller as compared to the octahedral entity.
