The reaction is oxidation - reduction type and takes place in presence of 50% aqueous orethanolic alkali One molecule of the aldehyde (missing of a- hydrogen atom )oxidizes, to corresponding carboxlic acid and the other is being reduced to the corresponding alcohol.Mechanism : the mechanism involves two distinct steps Nucleophilic attack and hydride ion transfer.
