Chemistry - Carbonyl compounds Question with Solution | TestHub

Aldehydes are more reactive than ketones due to $+\mathrm{I}$ effect of $-{\mathrm{CH}}_3$ group. There are two $-{\mathrm{CH}}_3$ group in acetone which reduces +ve charge density on carbon atom of carbonyl group. More hindered carbonyl group becomes less reactive. So in the given case ${\mathrm{CH}}_3\mathrm{CHO}$ is the right choice.
