WebRacemic acid, or, more properly, racemic tartaric acid, is a mixture of equal amounts of dextrorotatory and levorotatory tartaric acids; it is customarily designated D - or L -, or (+)- or (–)-, respectively, tartaric acid. The process by which an optically active substance is transformed into the corresponding racemic modification is known ... WebMay 13, 2024 · Optical activity refers to whether or not a compound has optical isomers. A coordinate compound that is optically active has optical isomers and a coordinate compound that is not optically active does not have optical isomers. As we will discuss later, optical isomers have the unique property of rotating light.
