Fluorene /ˈflʊəriːn/, or 9H-fluorene is an organic compound with the formula (C₆H₄)₂CH₂. It forms white crystals that exhibit a characteristic, aromatic odor similar to that of naphthalene. Despite its name, it does not contain the element fluorine, but rather it comes from the violet fluorescence it exhibits. For commercial purposes it is obtained from coal tar.^[3] It is insoluble in water and soluble in many organic solvents. Although sometimes classified as a polycyclic aromatic hydrocarbon, the five-membered ring has no aromatic properties.^{[citation needed]} Fluorene is mildly acidic.
