WebFeb 2, 1998 · Ethane (H3C–CH3) and Substituted Ethane The ethane molecule, C2H6, can exist in both the staggered and eclipsed conformations where the staggered conformation is slightly more stable. The differences in these two conformations for ethane can easily be seen by viewing them both on the screen simultaneously. WebIt is just that the staggered conformations are more energetically favored. In a system where there is ample energy to allow ethane to surpass the energy barrier necessary to get it …
