WebA racemic mixture shows different properties from enantiomer. Achiral Molecules. Achiral is the reverse of chiral. A molecule or ion is achiral if it is superimposable, i.e. it can be superimposed on its mirror image. They have a plane of symmetry or a centre of symmetry. Achiral molecules having a stereocenter are known as Meso molecules. WebIn chemistry, a molecule or ion is called chiral (/ ˈ k aɪ r əl /) if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/ k aɪ ˈ r æ l ɪ t i /). The terms are derived from Ancient Greek χείρ (cheir) 'hand'; which is the canonical example of an …
