In Cannizzaro's reaction out of two moles, one makes salt of an acid the other makes
Correct answer: B. Alcohol
- A. Ester
- B. Alcohol
- C. Carboxylic Acid
- D. Alkane
Explanation
The Cannizzaro reaction is a disproportionation reaction of aldehydes that lack an α-hydrogen atom. In this reaction, two moles of the aldehyde react with a strong base (like NaOH or KOH) to produce one mole of a carboxylic acid and one mole of an alcohol.

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.
