WebEn tant qu'hydrocarbure, le cyclohexane est une molécule peu réactive. Cependant, la très grande majorité du cyclohexane est utilisée pour être catalytiquement oxydée en … WebAug 19, 2024 · Cyclohexane 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).
