Concept explainers
(a)
Interpretation: The oxidation number of the metal in the given compound has to be determined.
Concept introduction:
Coordination compounds: The compounds having coordination covalent bonds which form when metal ions react with polar molecules or anions.
Ligands: The ions or molecules that forms coordination covalent bond with metal ions in a coordination compound. Ligands should have minimum one lone pair of electron, where it donates two electrons to the metal. Metal atom accepts the electron pair from a ligand forming a coordination bond.
Oxidation number: The total number of electrons in an atom after losing or gaining electrons to make a bond with another atom. It indicates the charge of an ion.
