Cyclohexane is a cycloalkane with the molecular formula C6H12. Cyclohexane is non-polar. Cyclohexane is a colourless, flammable liquid with a distinctive detergent-like odor, reminiscent of cleaning products (in which it is sometimes used). Cyclohexane is mainly used for the industrial production of adipic acid and caprolactam, which are precursors to nylon. Cyclohexyl (C6H11) is the alkyl substituent of cyclohexane and is abbreviated Cy. WebSo again, this is the heat of combustion divided by the number of CH2 groups in kilojoules per mole. And this is a much better way to compare the stability of the cycloalkanes. Notice cyclopropane has the highest value here, 697. Cyclobutane goes down to 680, cyclopentane is 658 and cyclohexane is approximately 653.
