2CH₃COCH₃ □(→┴dil NaOH ) CH₃C(OH)CH₂COCH₃ is the aldol condensation.
Explanation:
- Aldol condensation is the reaction where eto molecules of ketone undergoes condensation with each other in presence of dilute base forming a compound with both aldehyde and alcohol group.
- The presence of alpha hydrogen is must for the reaction to occur.
- The elemination of alpha hydrogen is must for the anion to form which is the reaction intermediate.
- In case of formaldehyde, there's no alpha hydrogen.
- Similarly in benzaldehyde there's no alpha hydrogen.
- So, the presence of alpha hydrogen in acetone makes it possible for acetone to undergo aldol condensation.
