WebOct 24, 2024 · The point group of the molecule, and the symmetry operations within that point group, can give clues as to whether the molecule is chiral. Symmetry operations of chiral molecules A chiral molecule cannot possess a plane of symmetry (\(\sigma\)), a center of inversion (\(i\)), or an improper rotation (\(S_n\)). WebMay 27, 2016 · A plane of symmetry is sufficient but not mandatory to give an achiral compound. But it should be clear that mirroring an image that contains an intrinsic mirroring plane will give the same. Another sufficient but not mandatory symmetry operation to generate a chiral compound is inversion. If some compound is point symmetric, it is … WebIf a molecule contains two or more chiral centers and does not have a plane of symmetry, it is chiral.

WebMar 26, 2016 · Any molecule that contains a chiral center will be chiral, with one exception: a meso compound. 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. WebAchiral molecules usually contain a plane of symmetry. With one tetrahedral estrogenic center, a molecule may or may not be chiral. With two or more stereogenic centers, a molecule is always chiral.
