Interpretation:
Carvone is present in many essential oils. However, its two enantiomers, viz
Concept introduction:
In an achiral environment, enantiomers have exactly the same physical and chemical properties. In a chiral environment, enantiomers have different physical and chemical properties. But depending upon the situation, the behavior of enantiomers can be slightly or dramatically different. Olfactory receptors are termed as smell receptors; the protein capable of connecting to odor molecules plays an important role in the sense of smell. In order to detect the smells of enantiomers of a compound, the olfactory receptors must be chiral.

- Draw the correct structure for (2S,3R)-2,3-diiodopentane. Show stereochemistry clearly. To ensure proper grading, explicitly draw all four groups, including wedge/dash bonds, around a chirality center.

- The quantitative differences in biological activity between the two enantiomers of a compound are sometimes quite large. For example, the D isomer of the drug isoproterenol, used to treat mild asthma, is 50 to 80times more effective as a bronchodilator than the L isomer. Identify the chiral center in isoproterenol. Why do the two enantiomers have such radically different bioactivity?arrow_forward5.69 Carvone is present in many essential oils. It is chiral, and its two enantiomers are shown here. Even though they are enantiomers, they have different odors. The (-) enantiomer smells like spearmint, whereas the (+) enantiomer smells like caraway seeds.

- It is possible for a compound to be chiral even though it lacks a carbon atom with four different groups. For example, consider the structure of following compound which belongs to a class of compounds called allenes. This allene is chiral. Draw its enantiomer. Me Me.

I know enantiomers are mirror images that can't be placed one on top of the other. I also know diastereomers are non-mirror images. Then when diastereomers are flipped 180 degrees they can be considered "the same". Why couldn't that be said for enantiomers too when flipped 180 degrees? Thank you!arrow_forward
