A ketone is a compound containing a carbonyl functional group bridging two groups of atoms. The general formula for a ketone is RC(=O)R' where R and R' are alkyl or aryl groups.
IUPAC ketone functional group names contain "oxo" or "keto". Ketones are named by changing the -e on the end of the parent alkane name to -one.
