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 … WebDraw your molecule with wedges and dashes and then draw a mirror image of the molecule.
