A cyclohexane molecule in chair conformation. Hydrogen atoms in axial positions are shown in red, while those in equatorial positions are in blue. Cyclohexane conformations are any of several three-dimensional shapes adopted by molecules of cyclohexane. Because many compounds feature structurally similar six-membered rings, the structure and ...
The cyclohexanone–cyclohexanol mixture, called " KA oil ", is a raw material for adipic acid and caprolactam, precursors to nylon. Several million kilograms of cyclohexanone and cyclohexanol are produced annually. [8] It is used as a solvent in some brands of correction fluid. Cyclohexane is sometimes used as a non-polar organic solvent ...

A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. [1] This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes. A Newman projection visualizes the conformation of a chemical bond from front to back, with the front atom ...
trans -but-2-ene. Cis–trans isomerism, also known as geometric isomerism, describes certain arrangements of atoms within molecules. The prefixes " cis " and " trans " are from Latin: "this side of" and "the other side of", respectively. [ 1 ] In the context of chemistry, cis indicates that the functional groups (substituents) are on the same ...
Conformational isomerism. Rotation about single bond of butane to interconvert one conformation to another. The gauche conformation on the right is a conformer, while the eclipsed conformation on the left is a transition state between conformers. Above: Newman projection; below: depiction of spatial orientation.
Methylcyclohexane(cyclohexylmethane) is an organic compoundwith the molecular formula is CH3C6H11. Classified as saturated hydrocarbon, it is a colourless liquidwith a faint odor. Methylcyclohexane is used as a solvent. It is mainly converted in naphtha reformersto toluene.[4]
In physics and engineering, a free body diagram (FBD; also called a force diagram) [ 1 ] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition. It depicts a body or connected bodies with all the applied forces and moments, and reactions, which act on the body (ies).
