Question:
Which one of the following has an optical isomer ?
(en = ethylenediamine)
Which one of the following has an optical isomer ?
(en = ethylenediamine)
Updated On: Jul 2, 2022
- $\left[Zn\left(en\right)\left(NH_{3}\right)_{2}\right]^{2+}$
- $\left[Co\left(en\right)_{3}\right]^{3+}$
- $\left[Co\left(H_{2}O\right)_{4}\left(en\right)\right]^{3+}$
- $\left[Zn\left(en\right)_{2}\right]^{2+}$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Only option (2) is having non-super imposable mirror image & hence one optical isomer.

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
