Racemic is a term used in chemistry to describe a compound that contains equal amounts of two enantiomers (mirror-image isomers). Synonyms for racemic include "equimolar mixture," "racemate," "racemic mixture," and "racemoid." Other related terms include "chiral," which describes compounds that are not racemic and have a non-superimposable mirror image, and "enantioselective," which describes reactions or processes that preferentially produce one enantiomer over the other. Understanding the differences between these terms is important in both theoretical and practical chemistry, as enantiomers often have vastly different properties and effects.
