WebAug 31, 2024 · What is the difference of energy between anti and gauche conformation of n-butane? In butane the gauche-conformer is less stable than the anti-conformer by about 0.9 kcal/mol. This is due to a crowding of the two methyl groups in the gauche structure, and is called steric strain or steric hindrance. WebApr 6, 2024 · One more 60 rotation gives us the ‘anti’ conformation, where the 2 methyl groups are positioned opposite each other and steric repulsion is minimized. This is the lowest energy conformation for butane. The diagram shown below summarizes the relative energies for the different eclipsed, staggered, and gauche conformations.
