The complete, detailed mechanism for the given reaction is to be drawn. The main product of the reaction is to be predicted. Concept introduction: A carbonyl compound is reacted with enol or enolate to form a β-hydroxyaldehyde or β-hydroxyketone , followed by dehydration to give a conjugated enone is known as aldol condensation. Aldol reactions are not limited to just ketones and aldehydes . Other compounds that contain a polar π bond and have acidic α hydrogens also undergo a similar reaction. The final dehydration step in aldol condensation occurs via an S N 1cb mechanism.

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.
