Naming Amides For 1 amide,drop -icor -oic acid from the carboxylic acid name,add -amide. For 2 and 3 amides,the alkyl groups bonded to nitrogen are named with N to indicate their position. ■Cyclic Amides Reaction of-NH2 and -COOH on same molecule produces a cyclic amide,lactam. To name,add word lactam to the IUPAC acid name or replace the -ic acid of common name with-olactam. O CH? CH3CHC-N-CH2CH3 N-ethyl-N,2-dimethylpropanamide CH; N-ethyl-N-methylisobutyramide 4-aminopentanoic acid lactam y-valerolactam CH3 Naming Amides ◼For 1 amide, drop -ic or -oic acid from the carboxylic acid name, add -amide. ◼For 2 and 3 amides, the alkyl groups bonded to nitrogen are named with N- to indicate their position. ◼Cyclic Amides ⚫Reaction of -NH2 and -COOH on same molecule produces a cyclic amide, lactam. ⚫To name, add word lactam to the IUPAC acid name or replace the -ic acid of common name with -olactam.
