The number of unidentate ligands in the comples ion is called

An example of unidentate ligand is

Ligand in the complex [FeCN)_6]^(3-) ion is：

Explain the terms Unidentate ligand

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.

Why is geomefrical isomerism not possible in tetrahedral compounds having two different types of unidentate ligands with the central metal ion ?
