Answer
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.)
