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
why is it important to grind the NaOH pellets used in an aldol condensation reaction between p-tolualdehyde and p-acetyltoluene to a powder?
8. The Aldol condensation reaction can be used to synthesize an ingredient commonly found in commercially available sunscreens. The procedure for this reaction is given below. Benzaldehyde (3.0 mL) and acetone (1.0 mL) are combined in a 25.0 mL round bottom flask. 2.5 M NaOH(aq) (1.4 mL) was then added, and the reaction was stirred for 30 minutes at room temperature. The resulting precipitate was isolated, and recrystallized using ethanol. The isolated yield of the target product was 2.68 g,...
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

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?
In our Aldol condensation reaction, p-anisaldehyde and acetophenone were reacted in the presence of NaOH to form trans-p-anisalacetophenone. Provide a benchtop test that can enable a student to confirm that the correct product was obtained at the end of an aldol condensation experiment, and explain how the test will work.
