Why are ketones less reactive than aldehydes?

Question

Quizplus · Accepted Answer

Ketones are less reactive than aldehydes because of two factors: steric hindrance and electron donation. Ketones have two bulky alkyl groups attached to the carbonyl carbon, causing steric hindrance that makes them less reactive than aldehydes, which have only one alkyl group. Additionally, the two alkyl groups in ketones donate electron density to the carbonyl carbon, making it less electron deficient and less reactive than the carbonyl carbon in aldehydes.
