Question:
Which of the following does not show optical isomerism? (en = ethylenediamine)
Which of the following does not show optical isomerism? (en = ethylenediamine)
Updated On: Apr 18, 2024
- $[Co(en)_2Cl_2]^+$
- $[Co (NH_3)_3Cl_3]^0$
- $[Co(en)Cl_2(NH_3)_2]^+$
- $[Co(en)_3]^{3+}$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
As complexes of the type $\left[ MA _{3} B _{3}\right]$ can show geometrical isomerism knows as facmer isomerism and not optical isomerism. So here $\left[ Co \left( NH _{3}\right)_{3} Cl _{3}\right]^{0}$ can not show optical isomerism.

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.
