Concept explainers
(a)
Interpretation:
The specific relationship between the given pair of molecules is to be identified.
Concept introduction:
If two cyclic molecules have different molecular formula, they are unrelated molecules. If they have the same molecular formula, same connectivity, and can be interconverted by a chair flip, they are conformers. Configurational isomers are the isomers having the same connectivity of atoms but differ in spatial arrangement at chiral centers. If configurational isomers have different configuration at each chiral center, they are enantiomers. If they differ in configuration at some but not all chiral centers, they are diastereomers.
