The Aldol condensation reaction involves the formation of a:
Correct answer: A. β-Hydroxy aldehyde or ketone
- A. β-Hydroxy aldehyde or ketone
- B. α-Hydroxy aldehyde or ketone
- C. α,β-Unsaturated aldehyde or ketone
- D. A dicarboxylic acid
Explanation
The aldol reaction involves the nucleophilic addition of an enolate ion to another carbonyl compound. The initial product formed is a β-hydroxy aldehyde or a β-hydroxy ketone, which is the characteristic structure of an aldol addition product.

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.
