Strong and weak ligands list class 12

A ligand is an ion or molecule, which donates a pair of electrons to the central metal atom or ion to form a coordination complex. The word ligand is from Latin, which means “tie or bind”. Ligands can be anions, cations, and neutral molecules. Ligands act as Lewis bases (donate electron pairs) and central metal … See more Monodentate ligands are also called “one-toothed“ because they bite the metal atom only in one place. See more Lewis base which donates two lone pairs of electrons to the central metal atom is known as bidentate ligands. They are often referred to as a … See more Chelate effect explains the enhanced affinity of chelating ligands for central metal ion or atom compared to the affinity of nonchelating monodentate ligands for the same metal.
