Anthracene vs. Phenanthrene: What's the Difference?
Edited by Janet White || By Harlon Moss || Published on February 22, 2024
Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) composed of three linearly-fused benzene rings, whereas phenanthrene has three benzene rings in a unique angular arrangement.
Key Differences
Anthracene is a crystalline hydrocarbon known for its three linearly arranged benzene rings. In contrast, phenanthrene, also a hydrocarbon, is characterized by its three benzene rings in a fused angular formation.
In anthracene, the molecular structure allows for electronic delocalization across the linearly connected rings. Phenanthrene's angular structure, on the other hand, creates a different electronic configuration.
Anthracene is utilized in the production of dyes, pigments, and the synthesis of other chemicals. Phenanthrene, while also used in chemical synthesis, has unique applications due to its distinct structure.
The reactivity of anthracene is influenced by its linear structure, making it a component in various chemical reactions. Phenanthrene's angular structure affects its reactivity and interaction with other compounds.
Both anthracene and phenanthrene are derived from coal tar, but their differing structures lead to varied uses in scientific and industrial applications.
