Cyclohexane twist
Webformation of cyclohexane, including the axial and equatorial hydrogens, are provided in Figure 6.13. The chair conformation of cyclohexane is not rigid. It can convert to a twist boat comformation and then to a new chair conformation in a process termed ring-flipping, as shown Figure 6.14 (not all the hydrogens are shown for clarity).

The 6-vertex edge ring does not conform to the shape of a perfect hexagon. The conformation of a flat 2D planar hexagon has considerable angle strain because its bonds are not 109.5 degrees; the torsional strain would also be considerable because all of the bonds would be eclipsed bonds. Therefore, to reduce torsional strain, cyclohexane adopts a three-dimensional structure known as the chair conformation, which rapidly interconvert at room temperature via a process known as a chair … WebThere is a peak/local maximum at the boat conformation (C), and there are valleys/local minimums at the twist-boat conformations (B). In addition, cyclohexane conformations can be used to indicate if the molecule has any 1,3 diaxial-interactions which are steric interactions between axial substituents on the 1,3, and 5 carbons.

Professor Davis demonstrates the boat and twist boat conformations of cyclohexane and how they affect the process of ring flips … WebCyclohexane twist conformation. Starting with the boat conformation and moving the flagpole hydrogens apart results in this conformer. Twisting not only relieves the steric strain between the flagpole hydrogens but also …
WebFigure 4.4. 1: Paste Caption Here. The constrained nature of cyclopropane causes neighboring C-H bonds to all be held in eclipsed conformations. Cyclopropane is always at maximum torsional strain. This strain can be illustrated in a Newman projections of cyclopropane as shown from the side.
