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

(a) It is a neutral ligand

(b) It is a didentate ligand

(c) It is a chelating ligand

(d) It is a unidentate ligand

Choose the correct option
1. (a, b)
2. (b, c)
3. (c, d)
4. (a, c)

Co(en)33+  and cis-Co(en)2Cl2+are optically active compounds because their mirror images are non-superimposable isomer.

Hence, (a) and (c) are correct choices.

The molecular formula of ethane-1, 2-diamine is

                             CH2NH2  |CH2NH2

(a) Ethane-1, 2-diamine is a neutral ligand due to the absence of any charge.

(b) It's a didentate ligand due to the presence of two donor sites one at each nitrogen atom of

the amino group.

(0) Itis'a chelating, ligand due to its ability to chelate with the metal

Hence, options (a), (b) and (c) are correct choices.
