The Cannizzaro reaction is a redox reaction in which two molecules of an aldehyde are reacted to produce a primary alcohol and a carboxylic acid using a hydroxide base. The reaction begins with hydroxide attack on the carbonyl carbon followed by deprotonation to give a dianion. Ueber den der Benzoësäure entsprechenden Alkohol. PPT – Cannizaro Reaction PowerPoint presentation | free to download - id: 53e170-ODVlM. The alkoxide then picks up a proton from water to provide the alcohol final product, while the caboxylate is converted to the carboxylic acid product after acid work-up.[1]. - Endothermic Vs.
