Identify the correct statements for the behaviour of ethane-1, 2-diamine as a ligand.

Options

A. It is a neutral ligand
B. It is a didentate ligand
C. It is a chelating ligand
D. It is a unidentate ligand

Answer

A, B, C

Explanation

Molecular formula of ethane-1, 2-diamine is
`{:(CH_(2)- overset(..)(N)H_(2)),("|"),(CH_(2)-overset(..)(N)H_(2)):}`
(a) Ethane-1, 2-diamine is a neutral ligand due to absence of any charge.
(b) It is a didentate ligand due to presence of two donor sites one at each nitrogen atom of amino group.
(c) It is a chelating, ligand due to its ability to chelate with the metal.
Hence, options (a), (b) and (c) are correct choices.
