Class 12 Chemistry Chapter 9 Coordination Compounds – Important Topics

Coordination compounds are those which consists of a central metal atom which is bonded to oppositely charged ions. These compounds do not dissociate into their constituent particles even when they are dissolved.

Double salts are formed when two salts in a stoichiometric ratio crystallize together from their saturated solution. Eg: Mohr’s Salt
Ligands are atoms or groups that are directly attached to central atoms. A ligand is a lewis base.

Isomers are two or more compounds with the same chemical formula but different atomic arrangements. It is of two types.

A. Stereomerism

Geometrical Isomerism
Optical Isomerism

B. Structural Isomerism

Linkage Isomerism
Coordinations Isomerism
Ionisation Isomerism
Solvate Isomerism

Metal carbonyls are homoleptic complexes in which carbon monoxide (CO) serves as the ligand.

Lewis Base: A Lewis base is a species that has a lone pair of electrons and can donate a pair of electrons to form a covalent bond.

Lewis Acid: The chemical species with empty orbitals that can accept a pair of electrons from the Lewis bases are called Lewis acids.
