If a polydentate is a ligand with more than one bonded atom, are the following: bidentate, tridentate, tetradentate, and hexadentate considered to be polydentates?

Yes, I believe those are examples of polydentates as those are ligands with 2, 3, 4, and 6 bonded atoms, respectively.

Yes polydentate is simply referring to how many molecules or atoms are bound to the ligand.

Yeah to add on, a monodentate would be a ligand with a single bond so it would only be capable of either binding to the central atom or an ion

We were told only to know three specific polydentates, correct?

Could someone please explain how you know if a molecule is polydentate or not? I’m still confused on this.

For example, in 17.33, we’re asked if the given molecules are polydenatate or not, and if they are, how many places can it bind simultaneously? Two of the molecules given were (b) CO3 -2 And (c) H20. The answer says b is bidentate while c is monodentate. Why is it that the O can bind to only one place for c but two places for b?
