Which of the following does not give aldol condensation
Correct answer: A. Methanol
- A. Methanol
- B. Ethanol
- C. Propanone
- D. 2-pentanone
Explanation
Aldehydes and ketones possessing α-hydrogen atoms react with a cold dilute solution of an alkali to form addition products known as aldols. Methanol has no α-hydrogen therefore it does not give aldol condensation reaction.

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.
