Organo fluorine compounds are organic chemical compounds that contain carbon and fluorine bonded in the polarized and remarkably strong carbon–fluorine bond. Organofluorine compounds are diverse, they can be fluorocarbons, perfluorinated, or aromatic fluoride compounds(such as 2-Bromo-4-fluorotoluene as described in the related link), among other possibilities. These compounds have a wide range of functions and can serve as refrigerants, pharmaceuticals, agrichemicals, surfactants, poisons, or pollutants.
