The major producer of the following reaction is
CH3CH=CH-CH2NH2
CH3-CHOH-CH=CH2
CH3-CHOHCH2CH2NHCHO
Major products of the following of the reaction are
CH3OH and HCO2H
A.
Aldehydes locking α – Hydrogen give cross cannizaro reaction. HCHO acts as hydride donor because it gives less sterically hindered tetrahedral Intermedia.
