A ketone is an organic compound that has a carbon atom with a double bond to an oxygen atom (this is called carbonyl functional group). This carbon atom must also have single bonds to two other carbon atoms.

Structure of a ketone

A ketone can be produced by oxidating a secondary alcohol.

A ketone will show a strong peak between 1690 and 1715cm-1 using infrared spectroscopy.[1]
