WebDec 30, 2016 · Hence, syn -1,2-dimethylcyclobutane is achiral. This can be explained well with point groups. The anti isomer has the point group C 2 which does not feature a plane or centre of symmery. The syn isomer has the point group C s whose only element of symmetry is a plane, hence it is achiral. You can read more about point groups in this … WebMay 9, 2024 · Some further examples to illustrate the point: The trans isomer is achiral, meaning this structure doesn't have enantiomers. However, it still has a cis diastereomer which can show chirality. An example closer home: Image courtesy I'm sure you must've figured out by now, that the carbon on top isn't a capable of showing optical isomerism.

Web3. Chiral molecules are asymmetric at one or more centres. Achiral molecules are symmetric at all the centres. 4. Chiral molecules rotate plane polarised light in a clockwise or anticlockwise direction. Achiral molecules don’t rotate plane polarised light in any direction. 5. The mirror image of a chiral molecule is a different molecule.
