The domestic organic chemistry textbooks use different numbers of contributing structures when introducing the resonance structures of benzene. This paper suggests that some of the related textbooks remove Dewar benzene and other ionic structures from the resonance structures of benzene, and adopt the correct resonance representation which constitutes only two Kekulé structures.

Key words: Organic chemistry, Benzene, Resonance structure, Kekulé structure, Dewar bezene
