2019-08-15 · The key difference between anthracene and phenanthrene is that anthracene is less stable compared to phenanthrene. Anthracene and phenanthrene are structural isomers. They have the same chemical formula, but the structure of the molecule differs from each other. However, both these compounds contain three benzene rings per molecule. CONTENTS. 1.
