WebThis is known as chiral resolution and its one of the two main strategies for the preparation of enantiopure compounds. A less common method is by enantiomer self-disproportionation . The second strategy is asymmetric synthesis: the use of various techniques to prepare the desired compound in high enantiomeric excess. WebFeb 2, 2024 · What happens is this; when light passes through matter, e.g. a solution containing either chiral or achiral molecules, the light is actually interacting with each molecule's electron cloud, and these very interactions can result in the rotation of the plane of oscillation for a ray of light.
