Vedclass · Answer

(B) Nucleophilic addition reactivity depends on the electrophilicity of the carbonyl carbon.$1$. Ketones are less reactive than aldehydes due to steric hindrance and the electron-donating effect of the alkyl group. Thus,Acetophenone $(S)$ is the least reactive.$2$. Among aldehydes,electron-donating groups (like $-CH_3$ in $p-$Tolualdehyde) decrease reactivity,while electron-withdrawing groups (like $-NO_2$ in $p-$Nitrobenzaldehyde) increase reactivity.$3$. Comparing the aldehydes: $p-$Tolualdehyde $(Q)$ Combining these,the increasing order of reactivity is: $S < Q < P < R$.

Arrange the following compounds in increasing order of their reactivity in nucleophilic addition reaction :
$(P)$ Benzaldehyde
$(Q)$ $p-$Tolualdehyde
$(R)$ $p-$Nitrobenzaldehyde
$(S)$ Acetophenone
