IUPAC name of `[Pt(NH_(3))_(2)Cl(NO_(2))]` is

Options

A. Platinum diaminechloronitrite
B. Chloronitrito-N-ammineplatinum (II)
C. Diamminechloridonitrito-N-platinum (II)
D. Diamminechloronitrito-N-platinate (II)

Answer

C

Explanation

Correct IUPAC name can be written as
the ligands present in the given coordination compound are
(i) `(NH_(3))` represented as amine
(ii) `Cl^(ɵ)` represented as chlorido
(iii) `NO_(2)^(ɵ)` represented as nitito-N
According to IUPAC rule, ligands are named in an alphabetical order before central atom. Prefex di-will be used to indicate the number of `NH_(3)` ligands present.
Oxidation state of metal is indicated by Roman numeral in parenthesis.
So, IUPAC name will be
diamminechloronitrito-N-platinum (II)
Hence, option (c) is correct.
