The Cannizzaro reaction, is a chemical reaction that involves the base-induced disproportionation of an aldehyde lacking a hydrogen atom in the alpha position.
acetaldehyde, CH3CHO has 3 ? hydrogens but in case of formaldehyde, HCHO there is no ? hydrogen present ,
hence formaldehyde undergoes cannizzaro's reaction whereas acetaldehyde does not.
