Interpretation: To explain the mechanism of ketone undergoes acid-catalyzed chlorination, acid-catalyzed bromination, racemization and acid-catalyzed deuterium exchange at the alpha carbon have similar rate constants.
Concept introduction: When a ketone or
The tautomers are the isomers that are in rapid equilibrium. A ketone exists in equilibrium with its enol tautomer.

- The reaction that occurs when the benzaldehyde you have is reacted in a basic environment is called the Cannizzaro reaction, and when it is reacted with cyanide, it is called benzoin production. Write down the reaction mechanisms of these reactions and explain why.arrow_forwardTo solve this problem, you need to read the description of the Hammett s, r treatment given in Chapter 15, Problem 92. When the rate constants for the hydrolysis of several morpholine enamines of para-substituted propiophenones are determined at pH 4.7, the r value is positive; however, when the rates of hydrolysis are determined at pH 10.4, the r value is negative.a. What is the rate-determining step of the hydrolysis reaction when it is carried out in a basic solution?b. What is the rate-determining step of the hydrolysis reaction when it is carried out in an acidic solution?arrow_forwardAn elimination step is involved in the synthesis of aromatic amino acids. We can also envision this occurring in a laboratory setting with a strong base. Provide a 1 step mechanism for this decarboxylation reaction. Note: under strongly basic conditions, hydroxide is a reasonable leavinggroup.arrow_forward
- The formation of Br2 from NBS first involves the reaction of NBS with HBr to form an iminol intermediate and molecular bromine. The intermediate then undergoes acid-catalyzed tautomerism to form succinimide, the byproduct of the reaction. Propose a curved-arrow mechanism for the conversion of NBS into succinimide that also accounts for the formation of Br2.arrow_forwardFor the given SN2 reaction, draw the organic and inorganic products of the reaction, and identify the nucleophile, substrate, and leaving group.arrow_forwardPlease draw the reaction (attached)and explain the mechanism of an SN2 reaction then identify the nucleophile, substrate and the leaving group.arrow_forward
- What is the mechanism for this transformation?arrow_forwardPropose the mechanism for this reaction.arrow_forwardPropose a series of reactions that would convert the provided starting material into the given product. The synthesis will take more than one step. For each reaction you use, show the reagents you would use and the product of that step. In each step, your desired product should be formed as the major product. Assume chiral products are formed as racemic mixtures. Your reactions should give the correct diastereomer. All carbons in the final products must come from the provided starting materials. In addition to the provided starting materials, you may use any reagents we have discussed. Hint, you’ll need to convert the starting materials into functional groups that you can connect together. I need help with this practice problem, thank you!arrow_forward
- According to the reactions studied thus far in this course: Ketones are able to be the substrate of a reduction reaction. Furthermore, ketones also are able to be the substrate of an oxidation reaction. True Falsearrow_forwardPlease draw out the mechanism for the reaction that involves the deprotonation of the acidic hydrogen on the ester followed by nucleophilic attack on the carbonyl carbon to form an enolate intermediate.arrow_forwardThe most stable conformation of most aldopyranoses is one in which the largest group, the CH2OH group, is equatorial. However, alpha-D-idopyranose exists primarily in a conformation with an axial CH2OH group. Write formulas for the two chair conformations of a-D-idopyranose (one with the CH2OH group axial and one with the CH2OH group equatorial) and provide an explanationarrow_forward
