Optical activity chirality

Webthat are optically active contain molecules that are chiral. Chirality is a property of a molecule that results from its structure. Optical activity is a macroscopic property of a collection of these molecules that arises from the way they interact with light. Compounds, such as CHFClBr, that contain a single stereocenter are the simplest to WebLiquids and solutions of chiral molecules such as sugars may be optically active if an excess of one enantiomer is present. In solution, each enatiomeric form will rotate light, and the net rotation depends on the relative quantities of …
