The mechanism for the given aldol addition reaction, which is catalyzed by acid is to be drawn. Concept introduction: The aldol condensation reaction can take place under acidic conditions. The carbon nucleophile cannot be an enolate anion as it is strongly basic. Under acidic conditions, the nucleophile can be an enol which is nucleophilic at α carbon atom. The enol is produced by two steps of proton transfer which is also called tautomerization.

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.
