Quizplus · Accepted Answer

The compound shown is a simple aldehyde with two carbons, and per IUPAC naming conventions, it should be named as a derivative of the parent chain of ethane. Therefore, the correct name is “ethanal” (option C). Options A and D are incorrect because the compound only has one carbon attached to the aldehyde functional group, not two. Option B is another potential name for ethanal, but it is an outdated naming convention. Option E refers to a ketone, not an aldehyde.
