There are two fundamental types of isomers, both of which we’ve now encountered: constitutional isomers and stereoisomers. Among the kinds of constitutional isomers we’ve seen are skeletal, functional, and positional isomers. Among the kinds of stereoisomers we’ve seen are enantiomers, diastereomers, and cis–trans isomers of cycloalkanes.

The student looked up the structures in CSB stockroom inventory and found more than one entry for 1,3 cyclohexanediol shown below. (The “diol” portion of the name indicates that there are two OH groups attached to the ring.)
