Meso compounds and racemic mixtures are examples where the … 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.

WebAn amino acid has the general formula H₂N-CH (R)-COOH, where R stands for the different acids. Notice that the central C atom is chiral — it has four different groups attached — so the molecule can exist as a pair of enantiomers (nonsuperimposable mirror images).
