Q. Ethylene diamine is an example of a ligand:

NTA AbhyasNTA Abhyas 2022

Solution:

Ligands are the neutral molecules, anions or cations which are directly linked to the central metal atom or ion in a complex ion.
Monodentate ligand: They have one donor atom i.e., they donate only one electron pair to the central atom or ion. Examples are $F^{-},Cl^{-},Br^{-},H_{2}O,etc.$
Bidentate ligand: The ligands which have two donor atoms i.e., they donate two electron pairs.
Ethylene diamine has the formula: $\overset{. .}{H_{2} N}-CH_{2}-CH_{2}-\overset{. .}{N}H_{2}$ , and it contains two donor atoms. So, it is a bidentate ligand.
