polydentates
If you're looking at a chemical equation, how do you know if it can be polydentate? For example HN(CH2CH2NH2)2?

Re: polydentates
It can be polydentate when there are multiple spaces for electrons to bind to a metal. You can tell if a chemical will be polydentate if it has multiple lone pairs to act as donating sites for the metals to grab on to.
In HN(CH2CH2NH2)2, each of the nitrogens has a lone pair which can be taken by the metal for bonding, making it tridentate.

Re: polydentates
I think that you have to draw the Lewis structure of the ligands. A polydentate ligand will have multiple atoms with a lone pair and an orientation that allows for those atoms to bind with a central atom in two places (this means that the atoms with lone pairs are close to each other).
