In a Cannizaro reaction, the intermediate that will be the best hydride donor is:
Correct answer: C. Option C
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Greater the charge density on carbon of the C−H group, the greater the tendency of the hydride to leave the carbon atom. Methoxy group present on the benzene ring is an electron releasing group, so (c) would be the best hydride donor among there.

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.
