The product of aldol condensation reaction followed by dehydration of butyraldehyde is to be predicted. Concept introduction: Aldol condensation is defined as a condensation reaction that involves the nucleophilic addition of an enolate ion to another carbonyl group to form a β − hydroxy ketone or aldehyde . The final product is commonly known as aldol because it contains both an aldehyde group and the hydroxy group of an alcohol.

Question

Predict the products of aldol condensation, followed by dehydration, of the followingketones and aldehydes.(a) butyraldehyde (b) acetophenone (c) cyclohexanone

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.
