Interpretation:

The formula for each of the given compounds:

Concept Introduction:

1. The positive ion is named first followed by the negative ion.
2. The ligands in the complex are written alphabetically irrespective of their charge.
3. When there are several ligands of the same kind, we use prefix such as di, tetra, hexa to show the number of ligands. An exception occurs when the name of the ligand includes a number such as ethylenediamine, hence to avoid confusion bis, tris, tetrakis are used instead of bi, tri, tetra and the name of the ligand is placed within brackets.
4. The oxidation state of the central metal is shown by a Roman numeral in brackets.
5. Complex negative ions end in −ate.
