**Methylcyclohexanones** are a group of three [isomers](/source/Isomer): 2-methylcyclohexanone, 3-methylcyclohexanone, and 4-methylcyclohexanone.[1] They can be viewed as derivative of cyclohexanone. They can be prepared by oxidation of [methylcyclohexane](/source/Methylcyclohexane) as well as partial hydrogenation of the corresponding [cresols](/source/Cresol). All are colorless liquids. The 2- and 3-isomers are [chiral](/source/Chiral).
