WebMay 1, 2024 · Rotation is possible around the double bond of an alkene but it requires between 60 and 70 kcal of energy. Without the addition of this energy, groups that start on one side of the double bond stay there. This is the basis of cis/trans isomerism. There are two forms; the cis and trans isomers.
