Question:
Which of the following complexes is optically active?
Which of the following complexes is optically active?
Updated On: Jun 14, 2022
- $ [Co(NH_{3})_{5}Cl]^{+} $
- $ [Co(NH_{3})Cl_{5}]^{3-} $
- $ cis-[Co(en)_{2} Cl_{2} ] $
- $trans- [Co(en)_{2}Cl_{2}] $
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
$cis [Co(en)_{2} Cl_{2}]$ does not have a plane of symmetry hence, it is a chiral molecule and optically active

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.
