The correct IUPAC name of [Pt(NH3)3Br(NO2)Cl]Cl is

  • triammine chlorobromonitroplatinum (IV) chloride

  • triamminebromochloronitroplatinate (IV) chloride

  • triamminebromochloronitroplatinum (IV) chloride

  • triamminebromochloronitroplatinum (II) chloride


C.

triamminebromochloronitroplatinum (IV) chloride

[Pt(NH3)3Br(NO2)Cl]Cl

Let the oxidation number of Pt is x.
x + 3(0)-1 - 1-1-1 = 0
                         x =+4
Hence, its IUPAC name is triammine bromochloronitroplatinum (IV) chloride.
