When aldehyde reacts with 50 % NaOH this reaction is called _.
Correct answer: D. Cannizaro reaction
- A. 2.4-NDPH reaction
- B. Aldol condensation reaction
- C. Clemmenson reaction
- D. Cannizaro reaction
Explanation
The Cannizzaro reaction is a disproportionation reaction of an aldehyde in the presence of a strong base, such as 50% NaOH. It involves the simultaneous oxidation of one molecule of aldehyde to the corresponding carboxylic acid and the reduction of another molecule of aldehyde to the corresponding alcohol. This reaction is named after the Italian chemist Stanislao Cannizzaro who discovered it.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
