Web25 mrt. 2024 · Ketones are highly reactive, although less so than aldehydes, to which they are closely related. Much of their chemical activity results from the nature of the carbonyl group. Ketones readily undergo a wide variety of chemical reactions. A major reason is that the carbonyl group is highly polar; i.e., it has an uneven distribution of electrons. WebAldehydes and ketones undergo addition reactions, including both nucleophilic as well as electrophilic addition. The C=O bonded carbon atom acts as an electrophilic (electron-deficient) site. Contrarily, the C=O bonded oxygen atom acts as a nucleophilic (electron-rich) reactive site in aldehydes and ketones.
