WebThe property of an organic compound that rotates plane polarised light (made by passing ordinary light through a Nicol prism) when it is passed through their solutions is known as optical activity, and the compounds are known as optically active compounds. Optical Activity of Racemic Mixtures 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

"WebThis property is called optical activity. Left- and right-handed enantiomers turn the polarization plane in opposite directions. The angle by which the polarization plane is rotated is called optical rotation. It is measured in degrees [°OR] with a polarimeter. Chiral molecules are characterized by the mirror image constitution of their atoms. " - Optical activity chirality
