Polydentate Lygands

Postby Isabel Gandarilla » Sat Nov 05, 2016 1:16 pm

When given a formula, how do you determine if a ligand is polydentate?

for example on hw problem 17.33 part b: CO 3^-2

To determine if a ligand is polydentate, consider the atoms with lone pairs of electrons on the ligands and also the shape of the ligands. If the lone pairs of electrons are distributed between different atoms on a ligand, then it is likely that the ligand will be polydentate.
I would draw the lewis structure to see which atoms have lone pairs.
