Consider only the formation of 5- and 6-membered rings. base Draw the organic product(s) of this intramolecular aldol condensation reaction. Consider only the formation of 5-and 6 membered rings. 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 . Draw one structure per sketcher. Add additional sketchers...
Aldol Condensation: 1) What is the purpose of using NaOH solution in this Aldol condensation? 2) Why acetic acid is used to wash the solid on the fiter? 3) Draw the structure of the product from the reaction: NaOH H +Acetone in ethanol
The “ Aldol Condensation" is a widely used reaction in organic chemistry. The first step involves the formation of an enolate in a base-catalyzed process. a) Draw the enolate that's derived from the following reaction. Use curved arrows to symbolize the flow of electrons where necessary. no NaOH NaOH
aldol condensation reaction Question 3: Is this reaction acid or base catalyzed? Tell the name of the base used. Question 4: What is the role of ethanol in the experiment? Question 5: Why 1.0 M HCl is used at the end of the experiment? Question 6: 4-nirobenzaldehye cannot undergo aldol condensation reaction by itself in the presence of strong base, give the reason for that?
Postlab Assignment for Minilab 34 “Preparation of Aldol Condensation Products” 1. Explain why benzaldehyde is expected to be the most reactive aldehyde among the three aldehydes used in this experiment. (used benzaldehyde, 4-methylbenzaldehyde, and 4-methoxybenzaldehyde) 2. What is the role of aqueous NaOH used in the experiment you carried out? 3. How would you change the procedures in this experiment if you wished to synthesize benzalacetophenone (C6H5CH=CHCOC6H5). Just indicate the two main organic starting materials. 4. Write a mechanism for...
(31) Show how the following compound can be synthesized using an Aldol Condensation reaction.
What enone product would you expect to obtain from intramolecular aldol condensation of hexanedial? 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. Rings containing fewer than 5 atoms are too strained to be formed in this reaction. If more than one structure fits the description, draw them all. Draw one structure per sketcher. Add additional sketchers...
Assume during the reaction of aldol condensation (the experiment that you performed in the lab), there is a contamination of acetaldehyde in one of the reagent bottle, predict how many products are going to be formed, show the chemical structure of all the predicted products. Reagent Bottle contains: 2 mL of 3 M NaOH solution, 1.6 mL of 95% EtOH and 0.212 g of benzaldehyde. Acetone is to be added.
