Amides are named from the parent carboxylic acid. The stem counts all the carbon atoms in the chain including the C=O carbon, and the ending -oic acid is replaced by -amide.
• HCONH2 is methanamide
• CH3CONH2 is ethanamide
• CH3CH2CONH2 is propanamide
For a secondary amide, the group attached to the nitrogen is named as a prefix with the locant N-, to show that it is bonded to nitrogen rather than to a carbon of the chain:
