Which of the following compounds undergoes aldol condensation most readily?

  1. A.Formaldehyde
  2. B.Benzaldehyde
  3. C.AcetaldehydeCorrect answer
  4. D.2,2-Dimethylpropanal

Solution

Aldol condensation requires aldehydes or ketones having at least one α\alpha-hydrogen atom. Acetaldehyde (CH3CHOCH_3CHO) has three α\alpha-hydrogens, whereas formaldehyde, benzaldehyde, and 2,2-dimethylpropanal lack α\alpha-hydrogens and undergo Cannizzaro reaction instead.
