Draw the structure of the major organic product of the following reaction. Predict whether the product will be an aldol or an enone. dilute NaOH 95% aq. ethanol, 50° . You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. Do not include lone pairs in your answer. They will not be considered in the grading. If no reaction occurs, draw the organic starting material. Θ Submit Answer Retry Entire Group 1 more group attempt remaining 44 S ? ChemDoodle

4) 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 + Hzo

Write structures for the carbonyl electrophile and enolate nucleophile that react to give the aldol below. OH f O • You do not have to consider stereochemistry. • Draw the enolate nucleophile in its carbanion form. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate multiple reactants using the + sign from the drop-down menu. ● + ChemDoodle O. #[ ] در ↑

Consider each elementary step present in the mechanism of an acid-catalyzed hydrolysis of a nitrile. Draw the organic intermediate after each elementary step. NOTE from Dr. Mahoney: Your mechanism will only cover the hydrolysis of a nitrile to an amide product. It will not cover the conversion of the amide to the final carboxylic acid H30* H₂O Step 3 Step 5 Step 4 11 N

Please help me answer questions 4 and 5 as seen in the photo!

Give me correct solution please.

What is the mechanism leading to the major product? I believe this is a nucleophilic acyl substitution correct me if i am wrong please.
