The set which does not have ambidentate ligand(s) is
Options
- AC 2 O 4 2 - , ethylene diammine, H 2 O
- BEDTA , 4 - NCS - , C 2 O 4 2 -
- CNO 2 - , C 2 O 4 2 - , EDTA 4-
- DC 2 O 4 2 - , NO 2 - , NCS -
Correct answer
A. C 2 O 4 2 - , ethylene diammine, H 2 O
Step-by-step solution
Ligand which has two different donor atoms and either of the two donor atom is attached to the metal during complex formation is called ambidentate ligand. Among the given ligands NCS - SCN -   and     NO 2 - ONO - are ambidentate ligands C 2 O 4 2 -   bidentate ,ethylenediamine(bidentate) and H 2 O (monodentate) ligands are not ambidentate.
