7.4 Properties of Chiral Molecules: Optical Activity

7.4 Properties of Chiral Molecules: Optical Activity. Optical Activity. A substance is optically active if it rotates the plane of polarized light. In order for a substance to exhibit optical activity, it must be chiral and one enantiomer must be present in excess of the other. Light.
