(A) The reactivity of aldehydes towards nucleophilic addition reactions depends on two main factors: steric hindrance and electronic effects.$1$. Steric hindrance: As the size of the alkyl group attached to the carbonyl carbon increases,the attack of the nucleophile becomes more difficult.$2$. Electronic effects: Electron-donating groups ($+I$ or $+M$ effect) decrease the electrophilicity of the carbonyl carbon,thereby reducing reactivity.In $C_6H_5CHO$ (Benzaldehyde),the phenyl group is bulky (high steric hindrance) and also exerts a $+M$ effect (resonance),which stabilizes the carbonyl carbon and reduces its electrophilicity.Therefore,the decreasing order of reactivity is: $HCHO > CH_3CHO > CH_3CH_2CH_2CHO > C_6H_5CHO$.Thus,$C_6H_5CHO$ is the least reactive.
