Abstract The “aromatic hydrocarbon” mental model held by high school students was evaluated by a second-order paper-and-pencil test and a semi-structured interview. We mainly focus on students' non-scientific mental model about “aromatic hydrocarbons and benzene's concept/structure/chemical properties”. The research shows that students' non-scientific models about aromatic hydrocarbon include 11 species in three categories; students' imagination and construction of the spatial structure are weak; students have insufficient understanding of the influence of the interaction between groups in organic compound structures on their chemical properties, the “nature-structure” model is imperfect; the mental model of organic chemistry is not yet integrated.
