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. WebMar 26, 2016 · If a molecule has a chiral center that is designated R, the chiral center will be S in the molecule's enantiomer. You need to be able to assign whether a chiral center is R or S. To do so, you need to follow three steps: Number each of the substituents on the chiral center carbon using the Cahn–Ingold–Prelog system. orc warband names https://sailingmatise.com
