WebThese are diastereomers, which is essentially saying it's a stereoisomer that is not an enantiomer. That's all it means: a stereoisomer, not an enantiomer. A stereoisomer's … WebCis and trans forms. The examples presented so far have concentrated on the simplest organic molecules, the alkanes.However, stereoisomers crop up in many of the other structural types of organic chemistry.For example, in the alkenes, two versions of 2-butene exist.They are traditionally called cis-2-butene and trans-2-butene or, in slightly more …
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 indicates that the functional groups (substituents) are on the same side of some plane, w… WebWhat term describes the structural relationship between cis-1, 2-dimethylcyclopentane and trans-1,3-dimethylpentane?
