Did you know?

WebCyclohexane is often depicted as a planar hexagon. However, with so much strain on the bonds, it prefers to adopt a chair conformation. This tutorial series will teach you everything from understanding these structures, drawing chair conformations, and ranking stability based on substituents. 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.
