Below are two examples of chiral molecules whose enantiomers demonstrate additional unique or detrimental properties. a) please draw a chemical strucfure for both enantiomers of thalidomide and point out which enantiomer is (R) and which is (,!. Also, describe now-ui-Tael{ of appreciation for the unique properties of enantiomers led to serious side effects when this molecule was used as a racemic drug. Roughly, what percentage of current drugs on the market are chiral? b) the unique smells of spearmint leaves and caraway seeds can be attributed to the same molecule -rcarvone. Please draw each enantiomer of carvone and briefly explain
