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. WebAbout this unit. Just like how your left foot doesn't quite fit your right shoe, molecules also can have properties that depend on their handedness! This property is called chirality.
