Chelating Ligands

Postby Tamera Scott 1G » Mon Nov 26, 2018 1:27 pm

Can someone explain why chelating ligands can bind cations tightly?

The reason for the tighter bond is because multiple coordinate bonds are formed due to the presence of several lone pairs on the chelate. This means that instead of a lone ligand which would only form one bond, the chelate compound can form several, increasing the overall strength.
