The question asks which of the following ligands can be polydentate? CO3 2- was said to be mono or bidentate and oxalate was said to be bidentate. For CO3 2-, why can it be mono or bidentate? For oxalate, where are the two places that the ligand can bind to the central metal? Is it the two oxygens that are single bonded or double bonded or either? I'm just a little confused because all the oxygens have lone pairs.
