Does Anthracene Have Resonance?

Anthracene is an aromatic hydrocarbon with the formula C14 H10 . It has multiple equivalent Lewis structures

Lewis structures
The Lewis structure was named after Gilbert N. Lewis, who introduced it in his 1916 article The Atom and the Molecule. Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.

, called resonance structures. The presence of resonance structures makes anthracene a rigid, planar molecule stabilized by delocalization of electrons.

How many resonance does anthracene have?

Anthracene will undergo delocalisation to give four resonance structures.

How do you know if there is resonance?

Because resonance structures are the same molecules, they must have: 1) The same molecular formulas. 2) The same total number of electrons (same overall charge). 3) The same atoms connected together.
