What is the role of dibenzalacetone in sunscreens?
Due to the conjugation of dibenzalacetone, the molecule is able to absorb UV rays. It is commonly found in sunscreen because, when applied, the dibenzalacetone is able to absorb the harmful UV rays from the sun before they can reach/harm the skin.
How will prepare bromodibenzalacetone?
To prepare bromodibenzalacetone, you can start by condensing benzaldehyde with acetone to form dibenzalacetone. Then, brominate the dibenzalacetone using bromine in the presence of a catalyst to obtain bromodibenzalacetone. Purification can be done through recrystallization using a suitable solvent.
Why it is important to maintain equivalent proportion of reagents in dibenzalacetone synthesis?
Maintaining an equivalent proportion of reagents in dibenzalacetone synthesis is important because it ensures the reaction proceeds efficiently, without any reagents being in excess or limiting quantities. This helps to maximize the yield of dibenzalacetone produced and prevents any wastage of reagents. Additionally, it helps to ensure the reaction conditions are controlled and reproducible, leading to consistent results.
What is the reason for the deep yellow colour of the dibenzalacetone?
The deep yellow color of dibenzalacetone is due to the presence of multiple conjugated double bonds in its structure. These conjugated double bonds absorb light in the visible region of the spectrum, causing the compound to appear yellow.
How would you modifyAldol Synthesis of Dibenzalacetone to make benzalacetone instead?
To modify the Aldol Synthesis of Dibenzalacetone to produce benzalacetone instead, you would use one equivalent of benzaldehyde as the aldehyde component, along with one equivalent of acetone as the ketone component. This would result in the formation of benzalacetone through the aldol condensation reaction.
Why you used 10 percent NaOH in synthesis of dibenzalacetone?
10% NaOH is commonly used in the synthesis of dibenzalacetone as a catalyst for the base-catalyzed aldol condensation reaction that forms the compound. The NaOH helps to facilitate the reaction by deprotonating the ketone and allowing it to react with the aldehyde, ultimately leading to the formation of the desired product.
Why you used 10 percent of sodium hydroxide in synthesis of dibenzalacetone?
A 10% concentration of sodium hydroxide is commonly used in the synthesis of dibenzalacetone to ensure that the reaction proceeds efficiently without causing side reactions or excess waste. This concentration provides the necessary alkaline environment for the reaction to occur while minimizing the formation of undesired byproducts.
Why is dibenzalacetone coloured?
It is because of the conjugate dienes. i.e. Double bond C single bond C double bonds. C=C-C=C etc. These conjugated dienes absorb light in the visible spectrum and in this case it happens to be pale yellow.

Why are there three isomers of dibenzalacetone?
There are three isomers of dibenzalacetone because of the different possible arrangements of the benzene rings and the carbonyl groups on the central carbon atom. These configurations lead to geometric isomers, where the relative positions of the benzene rings and carbonyl groups differ, resulting in three distinct isomeric forms.
