Tridentate||Tetradentate and Hexadentate Ligands Ambidentate||Flexidentate and Chelating Ligands||Coordination Number and Oxidation Number

A biodentate ligand has 3 coordination sites .

Assertion : Tetrahedral complexes having two different types of unidentate ligands coordinated with central metal ion will show geometrical isomerism . Reason : Geometrical isomerism arises in homoleptic complexes due to different possible geometric arrangement of the ligands .

Explain with two examples each of the following: coordination entity, ligand, coordination number, coordination polyhedron, homoleptic and heteroleptic

Assertion: In N_(2)H_(4) , any one N-atom can coordination with central metal cation in a coordination compound. Reason: N_(2)H_(4) can also act as ambidentate ligand.

The coordination number of a metal in coordination compound is
