Explain why aldehydes are more reactios than ketones.

Explanation

The carbonyl group is polar in nature

Lower positive charge on the carbon of carbonuyl group makes the aldehyde or keto less reactive towards nucleophilies. In ketones, the positive charge on the carbonly carbon is lowred by high + I effect of tw alkyl grougps in comparison to aldehyde in which one alkyl group is present. Further increases in the number of alkyl groups also increases eh steric hindrance making it less recative. Thus, in generalk, aldehydes are more reactive than ketones.
