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

A.[Co(en)₃]3+

B.[Co(en)₂ Cl₂]+

C.[Co(NH₃)₃Cl₃]✓ Correct

D.[Co(en) (NH₃)Cl₂]+

Explanation

Optical isomerism is exhibited by those complexes which do not have the elements of symmetry. From the given options 3 3 [Co(NH) Cl ] shows the meridional and the facial isomerism. Both the forms contains the plane of symmetry Hence, it exhibits optical isomerization. Hence, the correct answer is option (c)
