Warning
- Aldol reaction of a ketone: propanone ➔ 4-hydroxy-4-methylpentan-2-one. Same idea as aldehyde_to_hydroxyaldehyde.
removes an H from a next to C=O; the carbanion attacks the carbonyl C of a second molecule, forming a new C–C bond. - Not core syllabus — expect it only as an unfamiliar reaction to deduce.
- An unsaturated ketone + steam/
also gives a hydroxyketone — see unsaturated_ketone_to_hydroxyketone.
