Question

Why is optical isomerism not common in tetrahedral complexes?

Answer 1

1. Optical isomerism is not common in tetrahedral complexes because they typically exhibit high symmetry.
2. Most tetrahedral complexes have a superimposable mirror image, making them achiral.
3. For optical isomerism to occur, a complex must be chiral, and tetrahedral complexes with symmetric ligand arrangements usually do not have chirality.
4. However, optical isomerism can occur in tetrahedral complexes if the ligands are asymmetric or if there are different types of ligands (e.g., a mixture of monodentate and bidentate ligands), leading to non-superimposable mirror images.
