WebAboutTranscript. Ketones are named following IUPAC nomenclature. They are named by finding the carbonyl group and identifying it with a location number, if necessary, then adding the suffix "-one." The common name for ketones is determined by naming the alkyl groups attached to the carbonyl (in alphabetical order), then adding 'ketone'. 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.
