A structure for the condensation product of acetone with two molecules of benzaldehyde is to be proposed. Concept introduction: The reaction between the enolate of one aldehyde or ketone and the carbonyl group of a different aldehyde or ketone is known as crossed aldol condensation reaction. The reaction takes place only when one of the reactant has an alpha hydrogen atom.

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.
