http://research.cm.utexas.edu/nbauld/teach/ethane.html WebRotation around the C-2 to C-3 bond interconverts the s-trans and s-cis conformational isomers. The s-trans conformation has all 2p orbitals aligned parallel to one another to form a resonance-stabilized system. In the transition state for rotation, the π bonds are perpendicular to each other. As a result, they cannot interact and their ...
