Which of the following reactions is not given by ketones?
Correct answer: C. Polymerization
- A. Grignard reagent
- B. 2,4-DNPH
- C. Polymerization
- D. HCN
Explanation
Ketones generally do not undergo polymerization reactions under typical conditions. Polymerization typically involves the repetitive bonding of monomer units to form a long-chain polymer. While some aldehydes may undergo polymerization (e.g., formaldehyde), it is not a characteristic reaction for ketones.

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.
