WebThe carbonyl group has a wide variety of reaction pathways open to it. Because of its π bond, the carbonyl group undergoes addition reactions similar to those that occur with alkenes but with a few important differences. Whereas carbon-carbon double bonds are nonpolar, carbon-oxygen double bonds are polar.
