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

(d) It is a unidentate ligand

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

{[C o {(e n)}_{3}]}^{3 +} a n d c i s - {[C o {(e n)}_{2} C l_{2}]}^{+}

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

$C H_{2} — \overset{∙ ∙}{N H_{2}}$
$|$
$C H_{2} — \overset{∙ ∙}{N H_{2}}$

(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.
