How is a racemate formed
WebA racemic mixture or racemate is a mixture that contains an equal amount of two enantiomers. As light passes through the mixture, the enantiomers rotate the light equally but in opposite directions; this causes the mixture to be optically inactive. Louis Pasteur was the first to identify two types of isomers in tartaric acid.
