The class of compounds that contains a carbonyl group between two carbon atoms is called a ketone. A ketone is a compound that has a carbonyl group (C=O) bonded to two carbon atoms. This functional group is usually located in the middle of the carbon chain and can be represented by the general formula R-C(=O)-R', where R and R' can be any alkyl or aryl group. The presence of this functional group gives ketones their unique chemical and physical properties. To identify whether a compound contains a ketone, you can examine its molecular structure or use various laboratory tests specific to ketones, such as the iodoform test or the 2,4-dinitrophenylhydrazine test.
