Consider the alkene with the condensed structural formula CH 3 CH=CHCH 3.42: kJ/mol: Chyd: Kistiakowsky, Ruhoff, et al. In simple cases, such as 2-butene, Z corresponds to cis and E to trans. Although the H–H contact can be linked with smaller, relative to trans-, rotational energy barrier in cis-2-butene, we have proven that to rationalize this phenomenon one must account for changes in interactions between various fragments that constitute the entire molecule.
