alleryAldol condensation needs the molecule to carry at least one:
AGamma oxygen
BDelta nitrogen
CAlpha hydrogen
DBeta carbon
Answer & Solution
Correct answer: C. Alpha hydrogen
1. The reaction runs with dilute alkali as catalyst.
2. It works on the carbon next to the carbonyl group.
3. So at least one alpha hydrogen is needed.
