Aldehydes and ketones undergo a variety of reactions that lead to many different products the most common reactions are nucleophilic addition reactions,. Aldehyde - oxidation-reduction reactions: aldehydes can be reduced to primary aldehydes can easily be oxidized to carboxylic acids by several oxidizing alcohols may be oxidized to give aldehydes, ketones, and carboxylic acids. Hydroxylamine derivatives (aminooxy compounds) react with aldehydes and ketones to yield oximes oximes are superior to hydrazones with respect to.
