Interpretation:
The ranking of members of each of the following sets is to be determined.
Concept introduction:
The Cahn–In gold–Prelog (CIP) sequence rules, named for organic chemists Robert Sidney Cahn, Christopher Kelk Ingold, and Vladimir Prelog — alternatively termed the CIP priority rules, system, or conventions — are a standard process used in

- Rank the following groups in order of decreasing priority. a. – COOH, – H, – NH2, – OH b. – H, – CH3, – Cl, – CH2CI c. -CH2CH3, -CH3, -H, -CH(CH3)2 d. – CH = CH2, – CH3, – C ≡ CH, – Harrow_forwardHydrocortisone, a naturally occurring hormone produced in the adrenal glands, is often used to treat inflammation, severe allergies, and numerous other conditions. Is the indicated -OH group axial or equatorial?arrow_forwardThe shrub ma huang (Section 5.4A) contains two biologically active stereoisomers—ephedrine and pseudoephedrine—with two stereogenic centers as shown in the given structure. Ephedrine is one component of a once-popular combination drug used by body builders to increase energy and alertness, whereas pseudoephedrine is a nasal decongestant. a.Draw the structure of naturally occurring (−)-ephedrine, which has the 1R,2S configuration. b.Draw the structure of naturally occurring (+)-pseudoephedrine, which has the 1S,2S configuration. c.How are ephedrine and pseudoephedrine related? d.Draw all other stereoisomers of (−)-ephedrine and (+)pseudoephedrine, and give the R,S designation for all stereogenic centers. e.How is each compound drawn in part (d) related to (−)-ephedrine?arrow_forward
- Rank the following groups in order of decreasing priority. a.−COOH, −H, −NH2, −OH b.−H, −CH3, −Cl, −CH2Cl c. −CH2CH3, −CH3, −H, −CH(CH3)2 d.−CH=CH2, −CH3, −C≡CH, −Harrow_forwardRank the following groups in order of decreasing priority (1 = highest, 4 = lowest)arrow_forwardDraw the three constitutional isomers having molecular formula C7H14 that contain a five-membered ring and two methyl groups as substituents. For each constitutional isomer that can have cis and trans isomers, draw the two stereoisomers.arrow_forward
- Assign priorities to the groups in each set. (a) CH2OH and CH2CH2OH (b) CH2OH and CH=CH2 (c) CH2OH and C(CH3)3arrow_forwardAssign priorities to the groups in each set. (a) H CH3 OH CH2OH (b) CH2CH=CH2 CH=CH2 CH3 CH2COOH (c) CH3 H COONH3+ (d) CH3 CH2SH NH3+ CHOarrow_forwardConsider the following reaction. (a) Draw a structural formula for the compound with the molecular formula C8H12. (b) Do you predict the product to be the cis isomer, the trans isomer, or a mixture of cis and trans isomers? Explain. (c) Draw a suitable stereorepresentation for the more stable chair conformation of the dicarbaldehyde formed in this oxidation.arrow_forward
- What value is closest to the internal C-C-C bond angle of cyclohexane? Group of answer choices 90o 100o 110o 120oarrow_forwardA1. Draw the most stable conformations for: a)1-methyl-1-propylcyclohexane b)Trans-1-methyl-2-propylcyclohexane c)Cis-1-methyl-2-propylcyclohexanearrow_forwardConformer E is a (cis/trans) isomer. A conformational ring flip of conformer E will yield conformer F in which the substituent on carbon 1 will be (axial/equatorial/neither) and the substituent on carbon 3 will be (axial/equatorial/neither). Conformer (E/F) will be more stable.arrow_forward
