C. Smelling Chirality. Carvone Olfactory receptors in our noses, used for the detection of odors, are chiral. Therefore, in some cases, we can tell the difference between enantiomers by their odor. Carvone is one such compound that we can distinguish between the R and S enantiomer by their odor. 1. Identify the chiral center in carvone and draw the R and S enantiomers in the indicated boxes. 2. Smell both of the enantiomers of carvone and provide a brief description of their odors in the same boxes. Carvone is perfectly safe to smell as both enantiomers are found in various foods. R-carvone S-carvone

Draw both enantiomers of clopidogrel (trade name Plavix), a drug given to prevent the formation of blood clots in persons who have a history of stroke or coronary artery disease. Plavix is sold as a single enantiomer with the S configuration. Which enantiomer is Plavix?

Classify each compound as identical to A or its enantiomer.
