Enantiomers can be separated by means of

Options

A. fractional distillation
B. fractional crystallization
C. chromatography
D. None of these

Answer

D

Explanation

One consequence of the identity of most physical properties of enantiomers is of great partical significance. They cannot be separated by oridnary method: not bny fractional distillaiton because their boilding points are identical, not by fractional crystallization because their solubilities in a given solvent are identical (unless the solvent is optically active), not by chromatography because they are held equally strongly on a given adsorbent (unless it is optically active). The separation of a racemic modification into enantiomers (the resolution of a racemic modification) is therefore a special kind of job and requires a special kind of approcah.
