It proceeds in the same manner as ... WebJan 23, 2024 · Since the carbons in the cyclohexane ring is fully saturated with hydrogens (carbon is bound to 2 hydrogens and 2 adjacent carbons), no double bonds are formed in the cyclic ring. In contrast, benzene is only saturated with one hydrogen per carbon, leading to its molecular formula of C6H6. Cyclohexene is a hydrocarbon with the formula C6H10. This cycloalkene is a colorless liquid with a sharp smell. It is an intermediate in various industrial processes. Cyclohexene is not very stable upon long term storage with exposure to light and air because it forms peroxides. See more Cyclohexene is produced by the partial hydrogenation of benzene, a process developed by the Asahi Chemical company. In the laboratory, it can be prepared by dehydration of cyclohexanol. See more Cyclohexene is most stable in a half-chair conformation, unlike the preference for a chair form of cyclohexane. One basis for the cyclohexane conformational preference for a chair is that it allows each bond of the ring to adopt a staggered conformation.
