Question

Do square planar complexes exhibit optical isomerism?

Answer 1

1. Square planar complexes generally do not exhibit optical isomerism.
2. This is because square planar geometry is planar and symmetrical, which makes it difficult for such complexes to form non-superimposable mirror images (enantiomers).
3. Optical isomerism arises when a complex has chiral centres or an asymmetrical arrangement of ligands, leading to non-superimposable mirror images.
4. Very rare and special cases of optical isomerism can exist in square planar complexes, but this would require specific ligand arrangements or asymmetrical substituents that create chirality.

However, these cases are uncommon and not typically encountered in standard coordination chemistry.
