✓ Answer: D -one
The suffix attached to a hydrocarbon chain ending with a ketone is -one. Ketones are characterized by the presence of a carbonyl group (C=O) bonded to two carbon atoms. The suffix '-one' is used to indicate this functional group in the IUPAC naming system, such as in propanone (acetone) or butanone.
