Conformations of cyclohexane.
Cyclohexane is a colorless liquid hydrocarbon (C6H12) that occurs naturally in petroleum (crude oil), but is made commercially by combining hydrogen with benzene, using a catalyst. Cyclohexane is a type of a compound that exist in different conformations: two forms that differ only in the arrangement of their bonds, and may "flip" from one form to the other. A sample of cyclohexane may contain both. Melting point 6°C (43°F); boiling point 81°C (178°F).
