(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)

- Which of the following statement is NOT correct? 2 3 4 a. b. C. d. a b C d Constitutional isomers are compounds whose atoms are connected differently. Stereoisomers are compounds whose atoms are connected in the same order but with a different spatial arrangement. Diastereomers are stereoisomers that are mirror images. Molecules that are not identical to their mirror images are a kind of stereoisomers called enantiomers.arrow_forward1. What is the relationship between the following two compounds? a.stereoisomersb.identicalc.constitutional isomers 2. Assign the absolute configuration of the chirality center as R or S.arrow_forwardV. Newman projection of isomers of CH3-CHOH-CHOH-CHO (indicate absolute configuration of chiral centers) Number of chiral centers of each isomer: Which are enantiomers?

- 1. An object is chiral if it A. is superimposable on its mirror image B. is not superimposable on its mirror image C. has no mirror image D. is identical to each mirror image of itselfarrow_forward2. Mark any chirality centers (asymmetric carbons) with a *. How many stereoisomers are possible? Brarrow_forwardAssign 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_forward
- Which statement is correct about stereoisomers A, B, and C? H- CI CH3 S S CH3 A CI -H CI H A and B are enantiomers, C is a meso compound. A and C are enantiomers, B is a meso compound. A, B, and C are all meso compounds. Band C are enantiomers, A is a meso compound. CH3 R R CH3 B -H - CI H- H CH3 S R CH3 C CI -CIarrow_forwardConsiderthe image below. a. Draw the mirror image of structure I and label it as structure II.b. Are I and II chiral?c. What kind of stereocenters do they represent?arrow_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. R-carvone S-carvonearrow_forward
- Consider 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_forwardPart D. Do the two structures A and B of each pair drawn below represent the same molecule, constitutional isomers, or stereoisomers? If A and B are stereoisomers, further classify them as enantiomers or diastereomers.arrow_forward
