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. WebRelease notes: JetSurF2.0 consists of 348 species and 2163 reactions.

Axial hydrogens are those hydrogens that stick straight up or straight down parallel to an imaginary axis through the chair; equatorial hydrogens are hydrogens that stick out along the equator of the chair. Both types are shown here.

WebSep 24, 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). 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.

WebCyclohexane can have more than two substituents. Also, there are multiple six membered rings which contain atoms other than carbon. All of these systems usually form chair conformations and follow the same steric constraints discussed in this section.
