Which of the following complex species is not expected to exhibit optical isomerism?

Options

  1. ACo NH 3 3 Cl 3
  2. BCo en NH 3 2 Cl 2 +
  3. CCo en 3 3 +
  4. DCo en 2 Cl 2 +

Correct answer

A. Co NH 3 3 Cl 3

Step-by-step solution

Co NH 3 3 Cl 3 MA 3 B 3 type compounds exhibit facial as well as meridional isomerism. Since both isomers have a plane of symmetry they do not exhibit optical isomerism.
