The suffix for this molecule is "-al"
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 this carbons has a hydrogen connected to it, one of the functional groups is Aldehyde. Since we have an "$OH$" connected to a carbon that doesn't have bonds with other oxygens, the functional group is Alcohol. 2. Find the suffix we will use. (Look at the list in pages 84/85) The suffix for a molecule with an alcohol and an aldehyde is "-al". ** Aldehydes outrank alcohols in the nomeclature hierarchy (The order of the list.)
