(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.

- Assign the proper RIS-configurations to the following compound. CI CI O A. 1R,2S O B. 1S,2R O C. 1S,2S O D. 1R,2R O E. The compound does not have any stereocenters QUESTION 18 The compound in Problem 17 is a meso compound. O A. True O B. Falsearrow_forward2. 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.

What kind of stereocenters do they represent?arrow_forwardConsider CH3-CH(OH)-CH(OH)(Br). a.How many stereogeniccenters are in the molecule? b.How many stereoisomers are there for the compound? c.Draw the Fischer projection for each of the stereoisomer. Label each using I, II, etc. d.Which pairs are enantiomers? Which are diastereomers? e.Determine the absolute configuration of each chiral center in one pair of diastereomer.arrow_forwardExplain the difference between an enantiomer and an epimer. a. Enantiomers are non-superimposable mirror image structures. Epimers are diastereomers that differ only in the orientation of one chiral center. b. Epimers are non-superimposable mirror image structures. Enantiomers are diastereomers that differ only in the orientation of one chiral center.arrow_forward
