The textbook says that if a ligand is polydentate, then use the bis, tris, and tetrakis prefixes instead. How do you know if a ligand is polydentate?

A Ligand is a polydentate if it has two or more atoms that have lone pairs and can therefore bind to a metal ion. I found this website to be extremely helpful in defining the various types of ligands : https://www.chemicool.com/definition/ligand.html

A ligand is polydentrate when the electron lone pairs are found to be distributed among different atoms on a particular ligand rather than having the electron lone pairs on one atom, where it would not be polydentrate. Hope this helps
