Describe the following:Cannizzaro reaction - Toppr
Cannizzaro reaction: Aldehydes which do not contain hydrogen when treated with a concentrated solution of an alkali undergo self oxidation-reduction. As a result, one molecule of aldehyde is reduced to corresponding alcohol while the other molecule is oxidized to the corresponding acid. This reaction is called Cannizzaro reaction.
Cannizzaro reaction is not given by: - Toppr
Cannizzaro reaction is given by aldehydes that do not have a α hydrogen atom. Acetaldehyde ( C H 3 C H O ) has 3 α hydrogen atoms and thus doesnot undergo Cannizarro reaction. Was this answer helpful?

Formaldehyde[HCHO] undergoes Cannizzaro reaction: Give …
Formaldehyde [H C H O] undergoes Cannizzaro reaction because no α - hydrogen atom is present in formaldehyde. Note: Aldehydes and ketones having α - hydrogen atom undergo Aldol condensation reaction.
Cannizzaro is a disproportionation reaction. - Toppr

Which compound does not gives Cannizaro's reaction - Toppr
Cannizzaro reaction is given by aldehydes which do not contain an alpha hydrogen atom. In this reaction, a molecule of carbonyl compound is oxidized to carboxylic acid and another molecule is reduced to an alcohol. Acetaldehyde does not give Cannizaro's reaction as it contains an alpha hydrogen atom.
Cannizzaro reaction is not shown byCH_{3}CHOHCHO - Toppr
The aldehyde/ ketone, those do not contain α − H atom; show Cannizzaro reaction. In C H 3 C H O, carbonyl group is attached to C − a t o m having α − H; Hence, C H 3 C H O do not show Cannizzaro reaction.
