The suffix for this molecule is "-one"
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 to a carbon with a double bond, and there are no other oxygens, this functional group is Ketone. 2. Find the suffix we will use. (Look at the list in pages 84/85) The suffix for a molecule with a ketone group is "-one"
