Which one of the following can undergo aldol condensation reaction?
Correct answer: C. Acetaldehyde
- A. Formaldehyde
- B. Benzaldehyde
- C. Acetaldehyde
- D. Trimethylacetaldehyde
Explanation
Acetaldehyde has alpha hydrogen that is the hydrogen attached to the carbon adjacent to carbonyl carbon hence it undergoes cannizaros 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.
