What are the 3 geometric isomers of dibenzalacetone?
The three isomers of dibenzalacetone are cis-cis, cis-trans, and trans-trans.
What is the structure of dibenzalacetone?
C17H14O
Dibenzylideneacetone/Formula
What does dibenzalacetone look like?
Dibenzylideneacetone or dibenzalacetone, often abbreviated dba, is an organic compound with the formula C17H14O. It is a pale-yellow solid insoluble in water, but soluble in ethanol. Dibenzylideneacetone is used as a component in sunscreens and as a ligand in organometallic chemistry.
What is the possible stable isomer of dibenzalacetone?
cis-trans
The possible isomeric structures are cis-trans, cis-cis, trans-trans, and trans-cis as shown below. Out of all these, the cis-trans and trans-cis isomers are identical and thus they are considered as only one geometrical isomer of dibenzalacetone.

What is the density of Dibenzalacetone?
How do you make Dibenzalacetone?
There are stepwise method given below to prepare a sample of dibenzalacetone.
- Add 10ml of freshly distilled benzaldehyde and 20ml of acetone to a conical flask.
- Place the flask in a cold bath of water and then, with regular stirring, add 2.5ml sodium hydroxide dropwise.
- Keep the temperature at 30 oC.
How is Dibenzalacetone used in everyday life?
Dibenzalacetone is a yellow solid, which has found use in commercial sunscreen ointments. Benzaldehyde is used in a slight excess (2.2 equiv) in the recommended procedure. This allows the reaction to reach completion in a reasonable amount of time.
Is dibenzalacetone polar?
It is a pale-yellow solid that does not dissolve in water but dissolves in ethanol. It’s a non-polar, symmetrical molecule. In this article, we will study how to prepare a pure sample of dibenzalacetone in detail.
Which geometric isomer of dibenzalacetone is most stable?
Trans-trans is most stable bc less sterics. so yeah.
