Question

Why propanal is more reactive than propanone towards nucleophilic attack?

Answer 1

Answer:

propanone is sterically more hindered than propanal due to presence of alkyl group on

both side of carbonyl carbon making them

less reactive towards nucleophilic attack

both methyl group have electron releasing tendency due to -i effect . these alkyl group

make ketone less reactive by donating an

electron to a carbonyl group .

Answer 2

Answer: Propanone is sterically more hindered than propanal due to presence of alkyl group on both side of carbonyl carbon making them less reactive towards nucleophilic attack as both methyl group have electron releasing tendency due to +I effect. These alkyl group makes ketone less reactive by donating an electron to carbonyl carbon.
