Question
What is Chelate ligand? Explain Chelate Complex.
✓
Answer
$\rightarrow$ When multidentate ligands like en, $\ce{OX^{2-}, pn, ptn, (EDTA)^{4-}}$ form coordinate covalent bond with metal ion, it results into cyclic structure involving central metal ion.
Thus, the complex compound formed by ligand and metal ion having cyclic structure is called chelate complex and the ligand is known as chelate ligand.
$\rightarrow$ The stability of such chelate compounds is more than the stability of simple complex compounds
