All β -hydroxyaldehydes need to be drawn when mixture of benzaldehyde and hexanal is treated with aqueous sodium hydroxide. Concept introduction: Aldol addition reaction means the reaction between aldehyde which has an α hydrogen to form an addition product comprising of aldehyde and alcohol group in presence of base, namely sodium hydroxide. The name Aldol stands for aldehyde and alcohol (ald for “aldehyde” and ol for “alcohol”). The three steps involved in aldol addition reaction is, Deprotonation of α carbon Attach of enolate ion with the aldehyde (nucleophilic attack) Protonation of the alkoxide ion to give aldol product

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.
