Concept explainers
(a)
Interpretation:
The correct formula for the given names has to be given.
Dibromobis (ethylene diamine) cobalt (III) sulfate
Concept introduction:
Coordination number:
The coordination number is the number of ligand atoms bonded directly to the central metal ion in a complex ion.
Oxidation number: (Oxidation state) A number equal to the magnitude of the charge an atom would have if its shared electrons were transferred to the atom that attracts them more strongly.
- 1. The cation is named before the anion.
- 2. 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).
- 3. When more Ligands are present, Greek prefixes like di, tri, tetra, penta, and hexa to specify their number.
- 4. The oxidation number of the metal is represented in roman numerals immediately following the metal ion name.
- 5. If the complex ion is an anion, the metal name should end with –ate.
(b)
Interpretation:
The correct formula for the given names has to be given.
