Strategy • An aldehyde or ketone reacts with a primary amine, RNH 2, to yield an imine, in which the carbonyl oxygen atom has been replaced by the =N-R group of the amine • Reaction of the same aldehyde or ketone with a secondary amine, R 2 NH, yields an enamine, in which the oxygen atom has ...

Alcohols, Aldehydes, and Ketones

Alcohols  Alcohols are organic compounds that have a hydroxyl (-OH) group attached to a carbon  Classification of alcohols  Primary (1º) Alcohols: One carbon attached to the carbon that is attached to the -OH  Secondary (2º) Alcohols: Two carbons attached to the carbon that is ...
