Web22 feb. 2024 · Cyclohexane Ring Flip Ring flips take place to lower the energy of the ring's conformation, so in the example above, if the iodine were in an axial position, the molecule would undergo... WebTypically, in a cyclohexane ring, the chair conformation gives the lowest energy. However, in the cis-1,4-ci-tert-butylcyclohexane molecule, there are two large substituents located on the ring. These t-butyl groups are far too large to allow for a low energy value when they are in the axial position.
