Answer: vvv
Step-by-step explanation:
The retro-aldol reaction is a reverse aldol reaction, which means that it breaks down an aldol product into its original reactants.
In this reaction, a molecule of an aldol product undergoes a bond cleavage in the presence of an acid or base catalyst to form two carbonyl compounds, such as aldehydes or ketones, that were used to make the aldol product in the first place.
This reaction is called "retro" because it is essentially the reverse of the aldol reaction, which involves the formation of a new carbon-carbon bond between the carbonyl group of one molecule and the alpha carbon of another molecule.
