Configurational Isomers


When one is discussing isomers, they are talking about compounds that have something in common (their molecular formula) and also the way in which these isomers differ in a fundamental way. In the case of configurational isomers, the idea is that constraints placed in molecules by covalent bonds create alternatives in the way that atoms are arranged in three-dimensional space.

Unlike Constitutional Isomers which can differ tremendously, configurational isomers do not. The possess the same names since they are constituted the same.
