), wherein the carbonyl group is bonded to two alkyl or aryl groups, are somewhat less reactive. The polarity of the carbonyl group renders these compounds highly susceptible to nucleophilic addition reactions. The reactivity of aldehydes and ketones is differentiated, with aldehydes being more easily oxidized and attacked by nucleophiles. These compounds also show wide differences in their physical properties, including boiling points as a consequence of intermolecular forces and solubility in polar solvents due to hydrogen bonding.
Reactions and Applications of Aldehydes and Ketones
Aldehydes and ketones undergo nucleophilic addition, condensation, and redox reactions, so they are important intermediates in organic synthesis. Aldehydes are easily oxidized to carboxylic acids; ketones are resistant to oxidation under normal conditions. Both can be reduced to alcohols with reagents like NaBH

. The aldol condensation reaction is important in the synthesis of complex organic molecules because it creates β-hydroxy aldehydes or ketones.
These compounds have vast applications. Formaldehyde is used in resin production, acetone is an industrial solvent, and benzaldehyde adds flavor in food products. In pharmaceuticals, aldehydes and ketones are intermediates in synthesizing drugs and other bioactive molecules. Their role in industrial processes, such as polymer and dye production, highlights their importance in chemistry.
