Does acetone undergo self aldol condensation?

In the presence of an appropriate base, acetone can undergo self-aldol condensation to an alpha-beta unsaturated ketone. The base will react with acetone to generate an enolate which will react with another molecule of acetone to accomplish the self-aldol condensation.

Why does acetone not undergo self-condensation?

It is common practice in such a condensation reaction to select one carbonyl component which lacks α -Hydrogen atoms. Such a ketone/aldehyde cannot enolise and hence can’t act as the nucleophile in the reaction.

What is the aldol condensation product of acetone?

4-hydroxy-4-methylpentan-2-one.

What is a self-condensation reaction?

Self condensation: A condensation reaction in which two of the same molecule are condensed. This aldol condensation is a self condensation reaction because two molecules of acetone combine to form the product.

Why is the self-condensation of acetone unlikely in the presence of benzaldehyde?

e) Why is the self-condensation of acetone unlikely in the presence of benzaldehyde? Answer: a) This is an aldol addition. b) Using only 1 mole of benzaldehyde, the product would be the following. c) Using no acetone, no reaction will occur since benzaldehyde has no α-hydrogens.

What happens when acetone undergoes condensation with dilute alkali?

When treated with Ba(OH)2, acetone undergoes aldol condensation to form diacetone alcohol.

How can I reduce the condensation of acetone?

Minimizing any unwanted self-condensation of the ketone can also be achieved by taking care with the order in which the reagents are added. In the example below, the ketone would be added to a mixture containing the aldehyde and the base. This means that the ketone enolate forms in the presence of excess aldehyde.

Does aldol condensation between acetone and benzaldehyde require heat?

The more conjugated the product, the more stable the product, and the more favoured the reaction is going to be. Since dibenzylacetone is a highly conjugated aldol product, heat is not required for this reaction.

When acetone under goes condensation reaction the following compound is obtained?

When acetone is treated with Ba(OH)2, it gives diacetone alcohol. In this reaction two molecules of acetone condense. It is an aldol condensation reaction.

What happens when acetone reacts with NaOH?

Acetone contains alpha hydrogen atom. hence, when it is heated with dil NaOH solution, it undergoes aldol condensation reaction to form 4-methyl pent -3-en-2-one .

Why is acetone the limiting reagent in aldol condensation?

Acetone is the limiting reagent because it produces the least dibenzalacetone. Therefore, the moles of the limiting reagent is 0.025, and the mole of the product is 0.025.

What is the condensation product of benzaldehyde and acetone?

The product formed by aldol condensation between benzaldehyde and acetone is benzalacetone.
