The product of the base-catalyzed crossed aldol reaction between benzaldehyde and 3-pentanone and the product formed by its dehydration has to be drawn. Concept introduction: Aldol reaction is an addition reaction of aldehydes and ketones . Aldol reaction is a reversible reaction and occurs in the presence of a strong base like sodium hydroxide. One molecule (aldehyde or ketone) acts a nucleophile and attacks the electrophilic carbon center of the other molecule to give the addition product. The product is named β -hydroxy aldehyde if two aldehydes combine and β -hydroxy ketone if two ketones combine. If two different carbonyl compound used in an aldol addition, known as a crossed-aldol reaction.

Question

Drawing an Enol and a Ketone Formed by Hydration of an Alkyne Draw the enol intermediate and the ketone product formed in the following reaction.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
