The molecule 2 , 4 − pentanedione undergoes intramolecular aldol addition or not is to be stated. 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 a compound has two carbonyl functional groups that can react with each other, an intramolecular reaction readily occurs. The reaction leads to the formation of five or six-membered rings.

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.
