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.
