(a)
Interpretation:
The blank in the given sentence should be filled by suitable word.
Concept introduction:
Diastereomers are stereoisomers which are neither mirror images nor identical. If two stereoisomers are not enantiomers, then they are diastereomers. The pair of enantiomers have opposite configurations for each asymmetric centers in a compound.
(b)
Interpretation:
The blank in the given sentence should be filled by suitable word.
Concept introduction:
Diastereomers are stereoisomers which are neither mirror images nor identical. If two stereoisomers are not enantiomers, then they are Diastereomers.
(c)
Interpretation:
The blank in the given sentence should be filled by suitable word.
Concept introduction:
Diastereomers are stereoisomers which are neither mirror images nor identical. If two stereoisomers are not enantiomers, then they are Diastereomers.

- 2. Mark any chirality centers (asymmetric carbons) with a *. How many stereoisomers are possible? Brarrow_forwardC. 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.
