Four resonance structures of anthracene

Step by step solution

01

 Resonance structures

Two or more structures of a molecule differ in the placement of pi bonds and non-bonded electrons. The placement of atoms and sigma bonds stays the same.

02

Anthracene resonance structures

The delocalisation of the double bond in anthracene will create resonance structures. By the delocalisation of the double bond four resonance can be formed.

Thus, the four resonance structures of anthracene are as follows:
