Stereochemistry of elimination reactions through cyclohexane ring
Alicyclic compounds are those chemical organic structures that have carbon atoms (showing its aliphatic property) in a cyclic confirmation. They can be either saturated (having no free valence electrons) or unsaturated (they have free valence electrons that make the structure stable). In other words, these closed ring structures have three or more carbon atoms attached together forming a ring. The saturated alicyclic hydrocarbons has the general formula (CnH2n ). Here are some simple examples of alicyclic compounds:
Chair Conformation:
As per to the previous picture we can easily see that this conformation has three hydrogen atoms pointing up and other three pointing down .This form is the most stable conformation of all known …show more content…
This is less stable than the chair conformation in which we assume a torsional strain will be formed.
(1) The Flagpole hydrogen shows weak van der Waals strain
The boat conformation shows energy maximum not a lower energy.
Twist Boat Conformation: By twisting the boat conformation, the steric hindrance can be partially relieved, but the twist-boat conformer still retains some of the strains that characterize the boat conformer. In this conformation, slight angle strain, small eclipsing and steric strain.
Equatorial and axial bonds in cyclohexane:
At room temperature, cyclohexane, go through a conformational inter-conversion, all equatorial groups become axial and all axial groups become equatorial,.[but all “up” groups remain up, and all “down” groups remain down]. There are two types of bonds that hold the hydrogen atoms in the specific cyclohexane compound
① Equatorial Bonds: These bonds that that hold the hydrogen in the plane of the ring (around the equator) of the
