"WebCis-2-butene's net dipole can explain its boiling point differences to trans-2-butene. But if we're comparing the stability of both molecules then we're inspecting which one is more likely to be formed in a reaction. And in that sense trans-2-butene is more stable because it avoids the steric hindrance that cis-2-butene encounters. Hope that helps. " - How are alkenes formed
