WebFeb 4, 2024 · The most stable chair conformation is the one in which the largest groups occupy equatorial positions. In aldohexoses, the CH 2 OH group is the bulkiest substituent, so the most stable chair conformation will be the one in which this group occupies an equatorial position. This is the case for the chair conformation shown to the left. 7. Extra ... 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.
