Aldehydes are usually more reactive toward nucleophilic substitutions than ketones because of both steric and electronic effects. In aldehydes, the relatively small hydrogen atom is attached to one side of the carbonyl group, while a larger R group is affixed to the other side.
Hope it clears

Sterically large substituents in ketones hinders to attack nucleophile to carbonyl compoud and electronically 2 alkyl groups reduce the carbonly in ketones more affectI`ve than aldehydes.
