Cis konformation

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