(a)
Interpretation: The formulae for each of the given systematic names to be predicted.
Concept Introduction:
The cation is named before the anion.
Within a complex ion, the Ligands are arranged in an alphabetical order followed by the metal ion name. The anionic Ligand should ends with a letter –o, the neutral Ligand are called by the molecules (some common name for some exception).
When more Ligands are present, Greek prefixes like di, tri, tetra, penta, and hexa to specify their number.
The oxidation number of the metal is represented in roman numerals immediately following the metal ion name.
If the complex ion is an anion, the metal name should end with –ate.
To Identify: The formulae for each of the given systematic names to be predicted.
