WebIt had been accepted as early as the 1930s that the staggered conformations of ethane were more stable than the eclipsed conformation. Wilson had proven that the energy barrier between any pair of eclipsed and staggered conformations is approximately 3 kcal/mol, and the generally accepted rationale for this was the unfavorable steric ...

WebThe lower the potential energy, the more stable, so the staggered is more stable than the eclipsed. The energy difference between these two conformations, let me go ahead and … WebSep 24, 2024 · Typically, the staggered conformers are more stable and the eclipsed conformers are less stable. The least stable conformer will have the largest groups … WebWe have seen that staggered conformers of small hydrocarbons (e.g. ethane & butane) are more stable than eclipsed conformers and generally predominate at equilibrium. This structural preference is usually attributed to steric effects, and has been termed torsional strain (or Pitzer strain). girl with sunglasses clipart
