Question

Arrange ethanal , propanal, propanone, butanone in increasing order of their reactivity in nucleophilic addition reactions​

Answer 1

Butanone < propanone < propanal < ethanal

Additional Information:

as we move from ethanal → propanal → propanone → butanone, the +I effect of alkyl group increases and hence +ve charge on carbonyl carbon progressively decreases and hence the attack of nucleophile becomes slower and slower. also stearic hindrances due to alkyl groups increase.
