How ligands are classified ? Explain with suitable examples. |
|
Answer» Solution :Ligands can be classified into the following types depending upon the number of DONON atomsin the ligands. (a) Mono or unidentate ligands : Having only ONE donor atom. For example : `NH_(3)` nitrogen, is the only donon atom. (b) Poly or multidenate ligands : Having two ro more donor atoms. For example : Ethylene diamine (en) `underset("two")overset(**)(NH_(2))underset("donor")(CH_(2))-underset("atoms")(CH_(2))overset(**)(NH_(2))` `["EDTA"]^(4-)` is ETHYLENEDIAMINE tetra acetate six donor atoms (c) Ambident ligands: If a ligand had two or more donor atoms, while when a COMPLEX is formed only one donor atom is attached to the metal then it is CALLED ambidentate ligand. For example, `NO_(2)` has donor atom N and O out of the two only one donor atom is is linked to the metal as M-ONO or `MNO_(2)`. |
