- A 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_forwardAcyl transfer (nucleophilic substitution at carbonyl) reactions proceed in two stages via a "tetrahedral intermediate." Draw the tetrahedral intermediate as it is first formed in the following reaction. You do not have to consider stereochemistry. Include all valence lone pairs in your answer. Do not include counter-ions, e.g., Na+, I-, in your answer. In cases where there is more than one answer, just draw one.arrow_forwardHere is the same figure as in the previous two questions, but omitting the red circles.

Asn329 Which of the following roles is played by the imidazole side chain of His296? Pick the one best [ Select ] answer.arrow_forward
- The question is: "Draw the curved arrow mechanism for the reaction between pentan-2-one and (CH3)3O– in t-butanol to form an enolate. Draw all electrons and charges on both resonance structures. Then answer the question about the reaction." I got the initial arrows correct, but am not entirely sure what the carbanion intermediate would look like and then what the curved arrows would be to convert it to its final oxanion formarrow_forward4) We discussed in class how acetals are formed from a ketone and two equivalents of an alcohol, using an acid catalyst. Alternatively, would a strong base also catalyze (i.e. accelerate) the formation of an acetal? Explain why or why not, in the context of the reaction mechanism and potential intermediates. Naome, MeoH าาาา ← meo ome + Hzoarrow_forwardso we know that fischer esterification is a type of organic reaction that involves the formation of an ester from a carboxylic acid and an alcohol in the presence of an acid catalyst. am I correct to assume that a fisher esterification mechanism would look different than the above nucleophilic addition reaction? If they are different you you present the Fisher esterification mechanism of the reaction of acetic acid with pentanol in the presence of an acid catalyst, sulfuric acid and explain the mechanismarrow_forward
- In a Wittig reaction, a ketone or aldehyde reacts as an electrophile with a nucleophile called a Wittig reagent (or phosphonium ylide) to produce an alkene. The Wittig reagent is commonly synthesized first in a two-step process beginning with an alkyl halide, then reacted with the carbonyl compound. In this problem, you'll explore the mechanism of a multi-step synthesis to make an alkene using the Wittig approach.arrow_forwardDraw a mechanism for the conversion of glucose from its aldehyde form to its hemiacetal form and then to its methyl glycoside (acetal) form under acidic conditions. Show all bond breaking and bond forming steps; show all intermediates.arrow_forward(b) Consider the reaction of 1-bromobutane with a large excess of ammonia (NH3). Draw the reactants, the transition state, andthe products. Note that the initial product is the salt of an amine (RNH3+ Br - ), which is deprotonated by the excess ammonia to give the amine.arrow_forward
- Write a synthesis to convert ethane to the following compound shown below. Note: the synthesis has to be conducted in a basic medium throughout. No acidic conditions allowed.arrow_forwardStarting with ethene give a suitable reaction scheme to convert it into Ethyl ethanoate in 4 stepsarrow_forwardThe addition of water to aldehydes and ketones occurs rapidly, although it is not thermodynamically favored. What would be the product for the reaction above? Hint: Think of the self-ionization of water and the polarity of the carbonyl group.arrow_forward
