optical isomerism

Question

Which complex shows optical isomerism?

RankGuru · Accepted Answer

**Optical Isomerism** occurs in chiral complexes that lack a plane of symmetry.
- **$[Co(en)_3]^{3+}$**: This octahedral complex contains three bidentate ligands. The three rings wrap around the metal in a way that creates non-superimposable mirror images (called $\Lambda$ and $\Delta$ enantiomers).
- $[Co(NH_3)_6]^{3+}$ has three planes of symmetry (achiral).
- $[PtCl_4]^{2-}$ and $[Ni(CN)_4]^{2-}$ are square planar; they have the molecular plane as a plane of symmetry.
