Which is not true about Cannizzaro's reaction:
Correct answer: D. Dilute NaOH
- A. Self oxidation reduction
- B. Concentrated NaOH
- C. Disproportionation reaction
- D. Dilute NaOH
Explanation
Cannizzaro reaction is a chemical reaction named after Stanislao Cannizzaro that involves the base-induced disproportionation of two molecules of a non-enolizable aldehyde to yield a carboxylic acid and a primary alcohol.We use conc NaOH NOT DILUTE NaOH .50% concentrated NaOH solution is generally used in Cannizaro reaction as it is used for aldehydes which do not have α-H

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.
