Concept explainers
(a)
Interpretation:
The example of a complex that has coordination number 2 should be identified.
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.
Monodentate ligand is ligands which donate only one pair of electrons to form bond with metal. It only makes one bond with metal. Polydentate ligand forms two or more coordination bond with metal ions to form a complex.
Coordination number: The total number of ligands that forms bond with the metal atom.
Geometry of coordination compounds: The study of geometry of the coordination compound helps in understanding the physical and chemical property of the compound.
(b)
Interpretation:
The example of a complex that has coordination number 4 should be identified.
