Question

Which of the following does/do not exhibit optical isomerism?

• A. tetrahedral complexes
• B. square planer complexes
• C. octahedral complexes
• D. polynuclear complexes

Answer 1

Answer: (A), (B)

The correct options are
A square planer complexes
B tetrahedral complexes

Square planar complexes do not exhibit optical isomerism because the relative position of the ligands attached to the central metal atom is same with respect to each other and for the same reason some squares normal complexes also do not slow optical isomerism.

Also, tetrahedral complexes do not show optical isomerism as they have an all the ligand symmetrically positioned in the given plane.
