Question
Why does methanal not give aidol condensation while ethanol forms an aldol?
✓

Answer

This is because only those compounds which haie α – hydrogen atoms can undergo aldol condensation reactions. Ethanol possesses α – hydrogen and therefore undergoes aldol condensation. Methanal does not have α – hydrogen atoms, hence does not undergo aldol condensation reactions.
