Concept introduction:
Aldol reaction is an addition reaction of aldehydes and ketones. Aldol reaction is a reversible reaction and occurs in the presence of a strong base like sodium hydroxide. One molecule (aldehyde or ketone) acts a nucleophile and attacks the electrophilic carbon center of the other molecule to give the addition product. The product is named

- Draw the product formed when each organometallic reagent is treated with H2O.arrow_forward2-Pentylcinnamaldehyde, commonly called flosal, is a perfume ingredient with a jasmine-like odor. Flosal is an α,β-unsaturated aldehyde made by a crossed aldol reaction between benzaldehyde (C6H5CHO) and heptanal (CH3CH2CH2CH2CH2CH2CHO), followed by dehydration. Draw a stepwise mechanism for the following reaction that prepares flosal.arrow_forwardPlease come up with five ways to synthesize α,β-Unsaturated carbonyl compounds. Draw reaction sequences for each one.arrow_forward
