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. WebChiral molecules. This year’s Nobel Prize in Chemistry concerns the way in which certain chiral molecules can be used to speed up and control important chemical reactions.
