Distinguishing among enantiomers requires a technique that has a chiral attribute.
(a) Boiling point does not distinguish among two enantiomers.
(b) Optical rotation does have a chiral aspect, and thus can distinguish between two enantiomers.
(c) Because hexane is an achiral solvent, enantiomers have identical solubilities in hexane.
(d) Density is not a chiral property, and thus the two enantiomers have identical densities.
(e) The solubilities of two enantiomers in principle vary in an enantiomerically pure chiral solvent.
(f) Dipole moment is not a chiral property, and thus the two enantiomers have identical dipole moments.
(g) Because taste buds are chiral, they in principle differentiate among two enantiomers.
Characteristics of tautomerism (a) Tautomerism (cationotropy) is caused by the oscillation of hydrogen atom between two polyvalent atoms present in the molecule. The modificati
