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 centers rotate plane polarized light, and are designated as S or R depending on their connectivity. Chiral centers are a specific case of the more general stereocenters. On the MCAT the most common non-chiral stereocenter is an alkene with at least one non-hydrogen substituent on either end. Such stereocenters are designated as E or Z.
