The function of NaOH in Adol condensation & Cannizaro's reaction respectively is:
Correct answer: B. Base and nucleophile
- A. Nucleophile and electrophile
- B. Base and nucleophile
- C. Electrophile and nucleophile
- D. Nucleophile and base
Explanation
In the Aldol condensation, NaOH acts as a base by accepting a proton, and in the Cannizaro's reaction, it acts as a nucleophile by donating a pair of electrons to a carbonyl compound. So, it serves as both a base and a nucleophile in these reactions.

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.
