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.
