Chirality explained chemistry

WebDec 17, 2024 · A meso compound contains a plane of symmetry and so is achiral, regardless of whether the molecule has a chiral center. A plane of symmetry is a plane that cuts a molecule in half, yielding two halves that are mirror reflections of each other. By definition, a molecule that's not superimposable on its mirror image is a chiral molecule. WebChirality is a term that can be applied to molecular mixtures as well as to individual molecular species. Mixtures of chiral molecules can range from having 100 percent of …
