Aldehydes are typically more reactive than ketones

Aldehydes are more reactive than ketones in nucleophilic addition react

        Sterics

 

• Aldehydes are sterically less hindered than ketones (as hydrogen atom is smaller than any other organic group).

 

 

 Charge

• The carbonyl carbon in aldehydes generally has more partial positive charge than in ketones due to the electron-donating nature of alkyl groups. 

          Aldehydes only have one e^- donor group while ketones have two.
