Coordination Compounds

Coordination Number: The number of ligands attached to the central metal atom/ion in a coordination compound.

Ligands in Coordination Compounds

Ligand: According to Werner's theory, a ligand is an ion or molecule that binds to the central metal atom/ion in a coordination compound.

Types of Coordination Compounds

Homoleptic Coordination Compounds: Compounds in which a single type of ligand is attached to the central metal atom/ion.
Heteroleptic Coordination Compounds: Compounds in which multiple types of ligands are attached to the central metal atom/ion.

Werner's Theory of Coordination Compounds

Postulates of Werner's Theory:
- A metal atom/ion has a fixed number of available binding sites, known as the coordination number.
- Ligands can occupy these binding sites.
- The resulting compound has a specific geometric structure.

Theories of Coordination Compounds

Valence Bond Theory: Used to explain the formation and properties of coordination compounds by considering the overlap of atomic orbitals.
Crystal Field Theory: Used to explain the properties of coordination compounds in terms of the splitting of degenerate d-orbitals in a crystal field.

True or False Statements

Werner's Theory Basis: TRUE - Werner's theory of coordination compounds is the basis of modern inorganic and bio-inorganic chemistry.
Nomenclature Rules: TRUE - Nomenclature of coordination compounds follows specific rules.
Transition Metal Requirement: FALSE - Coordination compounds are not only formed by transition metals.
Isomerism in Coordination Compounds: TRUE - Isomerism can occur in coordination compounds.
Applications of Coordination Compounds: FALSE - Coordination compounds have many applications in our day-to-day life.
