IUPAC name of $[Pt {({NH}_{3})}_{2} Cl ({NO}_{2})]$ is-

1. Platinum diaminechloronitrite

2. Chloronitrito-N-ammineplatinum (ll)

3. Diamminechloridonitrito-N-platinum (ll)

4. Diamminechloronitrito-N-platinate (ll)

Hint: The given compound is neutral

Correct IUPAC name can be written as

The ligands present in the given coordination compound are

(i) (NH $_{3}$ ) represented as amine

(ii) Cl $^{-}$ represented as chlorido

(iii) NO $_{2}^{-}$ represented as nitrto-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 (ll)

Hence, option (c) is correct.
