The suffix for this molecule is "-oic acid".
Work Step by Step
1. Identify the functional group(s). *Hint: Look at the oxygens and the nitrogens, and compare the molecule and the groups on the list of functional groups. (Pages 84/85) Since we have an oxygen connected with a double bond to a carbon that has an "$OH$" connected to it too, one of the functional groups is Carboxylic acid. Since we have a nitrogen connected to a carbon and 2 hydrogens, one of the functional groups is an amine. 2. Find the suffix we will use. (Look at the list in pages 84/85) The suffix for a molecule with an carboxylic acid and an amine is "-oic acid". ** Carboxylic acids outrank amines in the nomeclature hierarchy (The order of the list.)
