WebRacemic mixture. In chemistry, a racemic mixture, or racemate ( / reɪˈsiːmeɪt, rə -, ˈræsɪmeɪt / ), [1] is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule or salt. Racemic mixtures are rare in nature, but many compounds are produced industrially as racemates. WebTo decide whether a compound should be optically active, we look for evidence that the molecules are chiral. The instrument with which optically active compounds are studied is …
