Concept explainers
a.
Interpretation:
For the below compound the chirality centers has to be labeledand number of chiral centers should be determined.
Concept introduction:
Chirality center:
When a carbon atom is bonded to four different groups, then that carbon is named as a chiral carbon and it is called as chirality center. Generally, the carbon atom contains tetrahedral valency, therefore it bonded to four atoms or molecules. The chiral center is bonded with four different elements or groups. If the single carbon atom is bonded to two or more identical group or atom, then it is also not considered as chiral carbon. In addition to this, if the carbon atom contains multiple bond then it does not able to bond with four different groups then itis not consideredto be as a chirality center.

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.
