Cyclohexan twist

WebOn cyclohexane, it really is arbitrary because all carbons can rotate. If there's a substituent (methyl, etc) then the carbon the substituent is connected to becomes C-1. Comment ( 1 … WebJun 6, 2014 · At room temperature, cyclohexane gives one signal because interconversion of chair forms occurs rapidly. At low temperatures, however, it gives a very complex 1 H NMR spectrum. At low temperatures interconversions are slow; the chemical shifts of the axial and equatorial protons are resolved, and complex spin-spin couplings occur.

The boat conformation comes from partial C-C bond rotations (only flipping one carbon up to convert the chair to a boat) of the chair conformation, and all the carbons still have 109.5º bond angles, so there are no angle strains.

WebCyclohexane 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).
