Quizplus · Accepted Answer

To determine if a ligand is bidentate or tridentate and capable of forming chelate rings, we need to look at the number of coordination sites or "arms" that the ligand has available to bond with a metal ion. Bidentate ligands have two arms, while tridentate ligands have three arms. Chelate rings are formed when a ligand uses more than one coordination site to bond with a metal ion, resulting in a more stable and rigid complex.
In option (a), the ligand has two coordination sites that can bond with a metal ion, making it bidentate. Option (c) has three coordination sites, making it tridentate. Both ligands are capable of forming chelate rings with a metal ion. Therefore, the correct answer is (a) and (c).
