Aldehydes are generally more reactive than ketones in nucleophilic addition because:
AAldehydes are basic, while ketones are acidic in nature here
BLess steric hindrance and less electron donation around the carbonyl
CAldehydes contain hydrogen, which is always more reactive in additions
DKetones are aromatic, which makes them stable to nucleophiles
Answer & Solution
Correct answer: B. Less steric hindrance and less electron donation around the carbonyl
Aldehydes have one H instead of an R group, less steric and less electron-donating, so more electrophilic at C=O.
