Which of following is not an ambidentate ligand?
CO
As we learnt in
Types of Ligands on the basis of Connectivity -
(i) Unidentate - ligand is bound to metal ion through a single donor atom.
eg:
(ii) Bidentate : when ligand can bind through two donor atoms
eg:
(iii) Polydentate - when ligand bind to two or more donor atoms
(iv) Hexadentate - type of polydentate having six donor atoms
(v) Ambidentate- which can ligate through two different atoms at a time
eg. &
- wherein
All ambidentate ligands are monodentate but all monodentate ligands are not ambidentate
Ambidentate Ligands can ligate through two different atoms at a time.
Of all the given, CO is the only ligand which can donate only through one atom i.e. C
