WebThe diaxial trans conformer has 3.6 kcal of steric strain, of course and is much less favored than the diequatorial conformer. The cis isomer is less stable than the trans because in it, one methyl must be axial. The cis isomer is therefore less stable than the trans by 1.8 kcal.
WebThe chair is the most stable conformation of cyclohexane, as the ring strain is minimized in it. These different conformations of a cycloalkane are known as conformational isomers or conformers. Conformers are formed by the continuous rotation of bonds in a cyclic structure without bond breaking.
