Definitions [2]
Define Enantiomers.
Stereoisomers which are non-superimposable mirror images of each other and rotate the plane of plane polarised light through the same angle but in opposite directions are known as enantiomers or enatiomorphs.
Define racemic mixture.
A mixture containing two enantiomers in equal proportions will have zero optical rotation, as the rotation due to one isomer will be cancelled by the rotation due to the other isomer. Such a mixture is called a racemic mixture or a racemic modification.
