"WebSo your initial assertion is correct, cis-but-2-ene is more polar than trans-but-2-ene because of the nonzero dipole moment. As such cis-but-2-ene should have stronger intermolecular forces than trans-but-2-ene causing cis-but-2-ene to have a higher boiling point. However you seem to have their boiling points mixed up.

WebThe cis/trans geometry of the final product is directly decided by the difference between conrotation and disrotation. Determining whether a particular reaction is conrotatory or disrotatory can be accomplished by examining the molecular orbitals of each molecule and through a set of rules.

WebIn addition, trans–alkenes are generally more stable than cis-alkenes, so we can predict that more of the trans product will form compared to the cis product. However, certain other eliminations (which we will not be studying) favor the least substituted alkene as the predominant product, due to steric factors. Such a product is known as the ... WebE–Z configuration, or the E–Z convention, is the IUPAC preferred method of describing the absolute stereochemistry of double bonds in organic chemistry.
