WebAldehydes and ketones undergo a variety of reactions that lead to many different products. The most common reactions are nucleophilic addition reactions, which lead to the formation of alcohols, alkenes, diols, cyanohydrins (RCH (OH)C&tbond;N), and imines R 2 C&dbond;NR), to mention a few representative examples. Reactions of carbonyl groups. WebNucleophilic addition reactions. Both aldehydes and ketones undergo nucleophilic addition with HCN/KCN. The carbon of the carbonyl group is partially positive due to the greater electronegativity of the oxygen. It acts as a source of attraction for nucleophiles, such as the cyanide ion, CN-.
