The most reactive of the following is
The most reactive of the following is
Open in App
Solution
The correct option is D Acetaldehyde
Aldehydes are generally more reactive than ketones. This is because, the two relatively large substituents, in ketones hinder the approach of nucleophile to carbonyl carbon than in aldehydes. Moreover, the two-electron releasing groups reduced the electrophilicity on carbonyl group.
Hence, the order of reactivity of the given compounds is as
C6H5COCH3<CH3COCH3<C6H5CHO<CH3CHO
Thus, acetaldehyde is the most reactive among the given compounds.
