Aldehydes 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 R2C&dbond;NR), to mention a few repre...
Naming Ketones Number the C chain so C=O has the lowest # Drop the final e from the alkane name and add -one Name these compounds: C-C-C-C-C C o 3-hexanone 4-methyl-2-pentanone Properties Both aldehydes & ketones have A carbonyl functional group. C=O is polar & their compounds ...
Aldehydes and ketones are prepared from (a) a primary or secondary alcohol, respectively, by catalytic dehydrogenation, possibly in combination with one or more condensation reactions, and/or from (b) an aldehyde or ketone, respectively, having a smaller number of carbon atoms than those to be ...
