- Nonconjugated , -unsaturated ketones, such as 3-cyclohexenone, are in an acid-catalyzed equilibrium with their conjugated , -unsaturated isomers. Propose a mechanism for this isomerization.arrow_forwardA problem often encountered in the oxidation of primary alcohols to acids is that esters are sometimes produced as by-products. For example, oxidation of ethanol yields acetic acid and ethyl acetate: Propose a mechanism to account for the formation of ethyl acetate. Take into account the reversible reaction between aldehydes and alcohols:arrow_forwardAcetal derivatives of aldehydes and ketones are prepared by an acid-catalyzed dehydration reaction with alcohols or diols. Using more pictures than words, draw a reaction and a mechanism that shows the formation of acetal.arrow_forward
- When trans-2-chloro-1-cyclohexanol is treated with a base, cyclohexene oxide is the product. However, when cis-2-chloro-1-cyclohexanol is treated with a base, the product is cyclohexanone. Write the mechanism for each of the two reactions.arrow_forwardAcid-catalyzed dehydration of 3-methyl-2-butanol gives three alkenes: 2-methyl-2- butene, 3-methyl-1-butene, and 2-methyl-1-butene. Propose a mechanism to account for the formation of each productarrow_forwardWrite a mechanism that accounts for the formation of ethyl isopropyl ether as one of the products in the following reaction. CI OEt HCI EtOH Write the mechanism for step one of this reaction. Show lone pairs and formal charges. Only the acidic hydrogen should be drawn out with a covalent bond. Write the mechanism for step two of this reaction (where the product of step one reacts with the solvent, ethanol). Show lone pairs and formal charges. Only the acidic hydrogen should be drawn out with a covalent bond. Write the mechanism for the last step of this reaction (formation of ethyl isopropyl ether). Show lone pairs and formal charges. Only the acidic hydrogen should be drawn out with a covalent bond. CI will act as the base in this reaction.arrow_forward
- Acetals are formed from the reaction of two alcohols with a carbonyl under acidic conditions. Acetal formation is faster with 1,2-ethanediol than with two methanol molecules. Choose the factor that explains the difference in reaction rates. A) The reaction with 1,2-ethanediol has a lower AH (enthalpy) of reaction. B) The reaction with 1,2-ethanediol has a higher AH (enthalpy) of reaction. C) The reaction with 1,2-ethanediol has a more favorable entropy of reaction.arrow_forwardDescribe how 3-methyl-1-phenyl-3-pentanol can be prepared from benzene. You can use any inorganic reagents and solvents, and any organic reagents provided they contain no more than two carbons.arrow_forwardPropose a mechanism for the reaction of(a) 1-methylcyclohexanol with HBr to form 1-bromo-1-methylcyclohexane.(b) 2-cyclohexylethanol with HBr to form 1-bromo-2-cyclohexylethane.arrow_forward
- When trans-2-chloro-1-cyclohexanol is treated with a base, cyclohexene oxide is the product. However, when cis-2-chloro-1-cyclohexanol is treated with a base, the product is cyclohexanone –arrow_forwardHydration of aldehydes and ketones can be catalyzed by acid or base. Bases catalyze hydration by: protonating the carbonyl oxygen making the carbonyl group more electrophilic employing hydroxide ion, which is a better nucleophile than water making the carbonyl group less electrophilic shifting the equilibrium position of the reaction to favor productsarrow_forwardThe following molecule can undergo keto–enol tautomerization upon addition of hydroxide. Draw the structure of the enol form and the mechanism by which it forms.arrow_forward
