A strong base is needed for Cannizaro's reaction as
Correct answer: C. base acts as nucleophile as well
- A. There is no functional group
- B. There are two functional group in reactant
- C. base acts as nucleophile as well
- D. base takes functional group H
Explanation
In the first step of the Cannizzaro reaction, the hydroxide ion acts as a nucleophile and attacks the carbonyl carbon of the aldehyde molecule. This forms a tetrahedral intermediate, which then loses a proton to the hydroxide ion, forming the negatively charged ion.

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.
