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
B. Structural 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.
