Ketones react with alcohols to yield products called acetals. Why does the all-cis isomer of 4-tert-butyl-1,3-cyclohexanediol react readily with acetone and an acid catalyst to form an acetal, but other stereoisomers do not react? In formulating your answer, draw the more stable chair conformations of all four stereoisomers and the product acetal for each one.
Gibbs free energy differences between axial-substituted and equatorial-substituted chair conformations of cyclohexane were given in Table 2.4. (a) Calculate the ratio of equatorial to axial tert-butylcyclohexane at 25C. (b) Explain why the conformational equilibria for methyl, ethyl, and isopropyl substituents are comparable but the conformational equilibrium for tert-butylcyclohexane lies considerably farther toward the equatorial conformation.
a model of cyclohexane in a chair conformation, and explain why the names “axial” and“equatorial’ are appropriate.
Draw both cis- and trans-l,4-dimethylcyclohexane in their more stable chair conformations. a. How many stereoisomers are there of cis-1,4-dimethylcyclohexane, and how many of trans-l,4-dimethylcyclohexane? b. Are any of the structures chiral c. What are the stereochemical relationships among the various stereoisomers of 1,4-dimethylcyclohexane?
Draw both cis- and trans-1,4-dimethylcyclohexane in their more stable chairconformations. (a) How many stereoisomers are there of cis-1,4-dimethylcyclohexane, and how many of trans-1,4-dimethylcyclohexane? (b) Are any of the structures chiral? (c) What are the stereochemical relationships among the various stereoisomers of 1,4-dimethylcyclohexane?
(A)Menthol, used to flavor various foods and tobacco, is the most stable stereoisomer of 2-isopropyl-5-methylcyclohexanol. Draw its most stable conformation. Is the hydroxyl group cis or trans to the isopropyl group? To the methyl group? (b) Neomenthol is a stereoisomer of menthol. That is, it has the same constitution but differs in the arrangement of its atoms in space. Neomenthol is the second most stable stereoisomer of 2-isopropyl-5methylcyclohexanol; it is less stable than menthol but more stable than any other stereoisomer. Write the structure of neomenthol in its most stable conformation.
