polydentate

[Anna Turk 1D]

How do you know when a ligand is polydentate? Such how is H2O monodentate?

[Darlene Luu 1H]

A ligand is polydentate when you have multiple ligands that are bonded to a central atom (usually a metal). H20 is monodentate because there are lone pairs on oxygen, meaning that there is one possible binding site between H2O and the central atom.

Hello,

A ligand is polydentate when it has multiple bonding sites. The main ones we need to know are (en) (bidentate), (ox) (bidentate), (dien) (tridentate), and (edta) (hexadentate). Additionally, if you are given a chelating ligand then it is polydentate.

Hope this helps!

Hi, are (en), (dien), (ox), and (edta) all neutral? meaning their oxidation numbers are 0? or are some of them charged?

it is when there is more than 2 ligand
