Which of the following ligands can be polydentate? If the ligand can be polydentate, give the maximum number of places on the ligand that can bind simultaneously to a single metal center: (a) HN(CH2CH2NH2)2; (b) CO3 2-; (c) H2O; (d) oxalate.

a) Tridentate ligand: This is because there are three Nitrogens in this structure that each have a lone pair. No other atoms have a lone pair.
b) Mono or bidentate Ligand: This is because CO3 can bind to one or two oxygen atoms.
c) Monodenate ligand: Even through oxygen has two lone pairs, the metal atom can only bind to one.
d) bidentate ligand: This is because there are two oxygens with a single bond and two oxygens with a double bond in this structure.

Did you have to draw out the Lewis diagrams to figure that out?

lavelle has a chart of the polydentate that we should know about on his website if that helps

Does anyone know if we are expected to have the whole chart memorized for the final?
