Vedclass · Answer

(D) The reactivity of carbonyl compounds towards nucleophilic addition depends on steric hindrance and electronic effects. $1$. Steric hindrance: As the number and size of alkyl or aryl groups attached to the carbonyl carbon increase,the attack of the nucleophile becomes more difficult. $2$. Electronic effects: Electron-donating groups decrease the electrophilicity of the carbonyl carbon. Formaldehyde $(HCHO)$ is the most reactive due to the absence of bulky groups. Benzaldehyde $(C_6H_5CHO)$ is more reactive than ketones. Among ketones,Acetophenone $(C_6H_5COCH_3)$ has one phenyl and one methyl group,while Benzophenone $(C_6H_5COC_6H_5)$ has two bulky phenyl groups. Due to maximum steric hindrance and the resonance stabilization of the carbonyl group by two phenyl rings,Benzophenone is the least reactive.
