WebSince a plane or point of symmetry involves a reflection operation, the presence of such an element makes an object achiral. One or more rotational axes of symmetry may exist in both chiral, dissymmetric, and achiral objects. WebMay 16, 2024 · 1. A meso compound is one which satisfies both of the following criteria: (1) it must have chiral centers and (2) it must have an internal plane of symmetry. On the other hand, an achiral compound is one which has an internal plane of symmetry. Thus you can say because a meso compound has an internal plane of symmetry, it is in fact achiral …

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.
