E In the equilibrium reaction of the conformations of 1,3-butadiene, what adequately explains the 15 kJ/mol energy barrier between the s-cis and s-trans conformation? 15 kJ/mol Sterics cause the s-cis conformation to be more stable and, therefore, higher in energy. (B) The л-bonds are not conjugated during the conversion of one conformation to the other. The s-trans is more stable because it is aromatic. The s-cis is less stable because it is non-aromatic. (E) Both the s-cis and s-trans are conjugated because all carbons are sp³-hybridized. 0° 90° Dihedral angle 180°
