WebMar 15, 2015 · Finally, we note that cis -2-butene is less stable that trans -2-butene for steric reasons. This allows us to place these C X 4 isomers in the following order of stability: 2-methylpropene is more stable than trans-2-butene which is more stable than cis-2-butene, which is more stable than 1-butene. When the substituent groups are oriented in the same direction, the diastereomer is referred to as cis, whereas, when the substituents are oriented in opposing directions, the diastereomer is referred to as trans.
