"WebPer- and polyfluoroalkyl substances (PFAS) are chemicals that contain bonds between carbon and multiple fluorine atoms. These strong carbon-fluorine bonds give PFAS useful chemical properties for making products oil-, stain-, and water-repellent, or non-stick. These same carbon-fluorine bonds also make PFAS extremely resistant to breakdown. " - Fluorine bond

WebFeb 23, 2024 · With other atoms, fluorine forms either polar covalent bonds or ionic bonds. Most frequently, covalent bonds involving fluorine atoms are single bonds, although at least two examples of a higher order bond exist. Fluoride may act as a bridging ligand between two metals in some complex molecules.

WebBonds that fall in between the two extremes, having both ionic and covalent character, are classified as polar covalent bonds. Such bonds are thought of as consisting of partially charged positive and negative poles. Example of a polar covalent bond: When a carbon atom forms a bond with fluorine, they share a pair of electrons.
