WebCyclohexane is generally used as an intermediate chemical. Specifically 54 percent of what is produced is used in the production of adipic acid for nylon-6/6, 39 percent for … WebCyclohexane is highly conformationally mobile, interchanging between the boat and chair forms many thousands of times per second. The most stable form of the cyclohexane ring is the chair form; in this conformer there is a greater interatomic distance between the equatorial and axial hydrogens than in the boat form.
Cyclohexane is a cycloalkane with the molecular formula C6H12. Cyclohexane is non-polar.

The substance is toxic to lungs, mucous membranes.
WebCyclohexane is a good example of a carbocyclic system that virtually eliminates eclipsing and angle strain by adopting non-planar conformations. Cycloheptane and cyclooctane have greater strain than cyclohexane, in large part due to transannular crowding (steric hindrance by groups on opposite sides of the ring).
