The IUPAC name of $[Pt (NH_{3})_{3} Br (NO_{2}) Cl] Cl$ is

Answer:

Solution:

The complex is $[Pt (N H_{3})_{3} B r (N O_{2}) Cl] Cl$ .

1. Ligands: triammine ( $N H_{3}$ ), bromido ( $B r^{-}$ ), chlorido ( $C l^{-}$ ), nitrito-N ( $N O_{2}^{-}$ ).

2. Oxidation state of Pt: Let it be $x$ . $x + 3 (0) + (- 1) + (- 1) + (- 1) = + 1$ (due to outer $C l^{-}$ ). So, $x - 3 = + 1$ , $x = + 4$ .

3. Alphabetical order of ligands: ammine, bromido, chlorido, nitrito-N.

4. IUPAC name: Triamminebromidochloridonitrito-Nplatinum(IV) Chloride.
