Aldehydes are more reactive than ketones due to +I effect of CH3 group. There are two CH3 groups in acetone which reduces +ve charge density on carbon atom of carbonyl group. More hindered carbonyl group too becomes less reactive. So, in the given case CH3CHO is the right choice.

Question

Accepted Answer

CH3CHO > CH3COCH3. Aldehydes are more reactive than ketones because ketones have two alkyl groups that exhibit +I effect, reducing the electrophilicity of the carbonyl carbon. Additionally, steric hindrance in ketones further decreases their reactivity. Thus, CH3CHO is more reactive than CH3COCH3.
