We have learned that isomers (molecules with the same molecular formula) can have different relationships, and these relationships can be made more clear by comparing IUPAC names. Constitutional isomers will differ in the main part of the name. Stereoisomers will differ only in the stereochemical prefix part of the name (cis/trans). Conformational isomers will actually have the same name, but different energies. Two structures that have the same names and the same energies are identical. What is the relationship between these two structures?
