WebChirality is an important geometric property relating to a molecule's symmetry. A chiral molecule is non-superimposable with its mirror image, and has a "handedness" (think of shoes, which specifically go with a right or left foot).

WebIn chemistry, when a molecule can have an exact mirror images of itself and be non-superimposable it is referred to as chiral. Keep in mind that the molecule (or the ion in the molecule) itself... 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.
