Monofluoride

A monofluoride is a chemical compound with one fluoride per formula unit. For a binary compound, this is the formula XF.
Organofluorine compounds.
Common monofluoride are organofluorine compounds such as methyl fluoride and fluorobenzene.
Inorganic compounds.
All the alkali metals form monofluorides. All have the sodium chloride (rock salt) structure and are soluble in water and even some alcohols. Because the fluoride anion is highly basic, many alkali metal fluorides form bifluorides with the formula MHF2. Sodium and potassium bifluorides are significant to the chemical industry. Among other monofluorides, only silver(I) and thallium(I) fluorides are well-characterized. Both are very soluble, unlike the other halides of those metals.
Selected inorganic monofluorides.
