How do we identify if a ligand is polydentate?

A polydentate ligand has multiple lone pair donating sites.

There are also common polydentate compounds that might be useful to know. They are mentioned in the textbook. Oxalate, edta, ethylenediamine, and diethylenetriamine are probably the ones that you should be familiar with.

Hope that helps!

A ligand is polydentate if it has multiple sites at which it can bind to a cation. The shape would look similar to an incomplete ring(s) with lone pairs at the ends.
