The structures of the two enone products obtained, in the approximate ratio of 9:1, when 2, 5-heptanedione undergoes intramolecular aldol condensation in the presence of aqueous NaOH, are to be given. Concept introduction: Aldehydes and ketones with α-hydrogen undergo a base catalyzed carbonyl condensation reaction in aldol condensation. In this reaction two molecules of the reactant combine by forming a bond between α-carbon of one molecule and the carbonyl carbon within the same molecule or of the second molecule. The aldol formed dehydrates on heating to yield α, β-unsaturated aldehyde or ketone as the product. To give: The structures of the two enone products obtained, in the approximate ratio of 9:1, when 2, 5-heptanedione undergoes intramolecular aldol condensation in the presence of aqueous NaOH.

Question

Steps and explanation please

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.
