Vedclass · Answer

(A) The reactivity of carbonyl compounds towards nucleophilic addition reactions depends on two factors: $1$. Steric hindrance: Smaller groups around the carbonyl carbon facilitate the attack of the nucleophile. $2$. Electronic effect: Electron-donating groups (like alkyl groups) decrease the electrophilicity of the carbonyl carbon by donating electron density,thereby reducing reactivity. $HCHO$ (formaldehyde) has the smallest hydrogen atoms attached to the carbonyl carbon,resulting in the least steric hindrance and the highest electrophilicity at the carbonyl carbon. Therefore,$HCHO$ is the most reactive towards nucleophilic addition reactions.
