Fluorene is a polycyclic aromatic hydrocarbon (PAH) with the formula C13H10. It is a white solid that is found in coal tar and is used in the production of plastics, dyes, and other organic chemicals. Fluorene is a relatively unreactive compound but can be oxidized, alkylated, and halogenated. It is a component of some polymers and can be synthesized by the reaction of benzophenone with cyclohexane. Fluorene is a known environmental contaminant and has been shown to be carcinogenic in animal studies. It is studied for its potential role in the formation of PAHs in combustion processes and its effects on human health.'
