The correct decreasing order of reactivity of , , and towards nucleophilic addition is: — Aldehydes Ketones and Carboxylic Acids Chemistry Question

💡 Solution & Explanation

Aldehydes are more reactive than ketones due to less steric hindrance and less +I effect. Between the ketones, $CH_3COCH_3$ is less sterically hindered than $C_2H_5COCH_3$, making it more reactive.
