Aldehydes are more reactive than ketones. Explain. |
|
Answer» Due to smaller +I effect of the alkyl group in a aldehydes as compared to large +I effect of two alkyl groups in ketones, the magnitude of positive charge on the carbonyl carbon is more in aldehydes that ketones. As a result nucleophilic addition reaction occur more readily in aldehydes that in ketones. As the number and size of the alkyl groups around C = O group increases, there is steric hindrance which makes the attack of the nucleophile on the carbonyl carbon more difficult. |
