(b) whether it is the (R) or (S) enantiomer that smells like spearmint? (c) With the information given in the drawings of carvone above, what can you add to your answers to (a) or (b)?

Like carvone, the two enantiomers of celery ketone smell differently. The R enantiomer smells like celery leaves, whereas the S enantiomer smells like licorice. Draw each enantiomer and assign its odor.
