Here we have discussed Chapter 9 of Class 12 Chemistry. To form a coordination complex, a molecule or an ion binds to the metal atom. Such an ion or molecule is called ligand. These ligands function as an electron-pair donor. Unidentate ligands are the ligands which have one donor atom. Bidentate ligands are the ligands which have two donor atoms. Tridentate ligands are the ligands which have three donor atoms. Hexadentate ligands are the ligands which have six donor atoms.
Class 12 is very crucial as the grades matter a lot. It is a factor that helps you decide your career. To score well, you need to prepare well for the exam.
