The following ligand is:

Options

Atridentate
Bhex dentate
Cbidentate
Dtetradentate

Correct answer

D. tetradentate

Step-by-step solution

The number of lone pairs that can be used by ligands is a measure of its denticity. In the given compound, both oxygen atoms and both nitrogen atoms are used as ligands and have lone pairs. Hence denticity is tetradentate.
