• B. Tetraammineplatinum(2+) ion
• C. Tetraammineplatinate(II) ion
• D. Tetraammineplatinate(2+) ion

Answer 1

The correct option is A Tetraammineplatinum(II) ion

Given, Complex is $\left[Pt\right[N{H}_3{]}_4{]}^{2+}$

As the complex is cationic the nomenculature ends with potassium (II) ions.

As the ligand $N{H}_3$ is repeated 4 times so, it is named as tetra ammine.

So the IUPAC Name:
