Which set or sets of isomers could be separated using crystallization or column chromatography?

Question

Quizplus · Accepted Answer

Both sets II and IV can be separated using crystallization or column chromatography because they have different physical properties (melting/boiling points) even though they have the same chemical formula. Sets I and III cannot be separated using these techniques because they are constitutional isomers, meaning they have different connectivity of atoms and therefore different chemical properties, not just physical properties.
