Answer 1

The IUPAC name of $[Pt(NO_2)(H_2O)(NH_3)_2]$ is diammineaquanitro platinum (I).

Explanation:

Rules for naming of the coordination compounds :

1. The ligand is named first.

2. The charge of metal indicated with the Roman numerals and enclosed in the parenthesis after metal name.

3. The ligands are named in alphabetical order before the metal ion.

4. Ligands that include a numerical prefix in the name use the prefixes bis for 2, tris for 3, or tetrakis for 4 to indicate their number.

In the given coordination compound, Pt is the platinum metal, $NO_2$, $H_2O$ and $NH_3$ are the ligands named as nitro, aqua and ammine respectively.If the oxidation state of platinum is x.

x+1(-1)+1(0)+2(0)=0

x=+1

IUPAC name of $[Pt(NO_2)(H_2O)(NH_3)_2]$ is diammineaquanitro platinum (I).
