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.

Cis–trans isomerism, also known as geometric isomerism or configurational isomerism, is a term used in chemistry that concerns the spatial arrangement of atoms within molecules. The prefixes "cis" and "trans" are from Latin: "this side of" and "the other side of", respectively. In the context of chemistry, cis … See more 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.
