ALIAKBER HAKIMJEE Aldol Condensation Lab #35 INTRODUCTION Benzaldehyde reacts with a ketone in the presence of base to give a α,β- unsaturated ketones. This is a typical of a crossed aldol condensation in which the intermediate undergoes dehydration to produce the resonance-stabilized unsaturated ketone. Crossed aldol condensations give a high yield because Benzaldehyde cannot react due to the
