WebApr 24, 2024 · However, the gauche conformer has a #"CH"_3, "CH"_3# repulsion. Thus, the gauche conformer is about #"4 kJ·mol"^"-1"# higher in energy than the anti isomer. You can see the energy differences graphically in the diagram below. You can interact with 3D models of the anti conformer here and of the gauche form here. WebButane-gauche interactions are the names given to this fundamental contact (of steric origin). Conclusion Since this gauche conformer is much more compact than the conformer of butane, it also has a relatively low molecular space and stronger intermolecular van der Waals interactions (due to its high surface/volume ratios).
