Just … Webq The cis or trans designation is based upon the relationship around the central, formally single C-C bond. q The s-trans conformation is more thermodynamically stable because the s-cis conformation has a steric repulsion between the two inside hydrogens. q However, both conformations are found at least to some extent. We will see that although ...
