Question 13

Name this molecule.

Answer 13

In a more complex molecule with a higher priority group that takes precedence over the carbonyl, we name aldehydes and keystones as a substituents, using the prefix oxo–. This is in reference to the carbonyl oxygen and applies for both ketones and aldehydes. Sometimes ketones may also be indicated with a prefix keto–.
