The carbonyl group (-CO) consists of a carbon atom that is joined to anoxygen by a
double bond. If the functional group is on the end of the carbon chain, the organic
compound is called a ketone. The simplest ketone is acetone, which contains three
carbon atoms. A ketonehas the suffix –one in itsIUPAC name.Exercise 1 - 10
