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.
Physical properties of Benzaldehyde (a) It is a colourless oily liquid. The boiling point of it is 179° C. (b) Benzaldehyde has smell of bitter almonds. (c) Benzaldehyde
