Benzene - CliffsNotes
Modern descriptions of the benzene structure coine resonance theory with molecular orbital theory. Resonance theory postulates that when more than one structure can be drawn for the same molecule, none of the drawn structures is the correct structure. The true structure is a hybrid of all the drawn structures and is more stable than any of them.

Benzene - Uses, Characteristics, Structure and Properties
Resonance in Benzene The resonance form of a compound is nothing but another way of representing the Lewis dot structure of that compound. Benzene shows resonance as it has more than one way to place double bonds in the ring. Benzene shows 2 resonating structures. Resonance forms or resonating structures only differ in the arrangement of electrons.

What is Resonance in benzene? - Quora
Resonance structures are drawn when just one structure does not represent the molecule well. Benzene consists of a six-meered ring that contains alternate double bonds. The pi electrons of the double bond are delocalised. The pi electrons are shared between the six carbon atoms. This is the reason for the excessive stability of benzene.
