Caesium fluoride or cesium fluoride is an inorganic compound usually encountered as a hygroscopic white solid. It is used in organic synthesis as a source of the fluoride anion.Caesium has the lowest electronegativity of all non-radioactive elements and fluorine has the highest electronegativity of all elements.aesium fluoride can be prepared by the reaction of caesium hydroxide (CsOH) with hydrofluoric acid (HF). The resulting salt can then be purified by recrystallization.
Hydrogen fluoride is a chemical compound formed from the covalent bonding of hydrogen and fluorine atoms. It has many commercial uses, including oil production and uranium production. It is corrosive, and can cause major damage to humans, including respiratory, liver, and kidney damage.ydrogen fluoride is a molecule that is formed from combining a hydrogen atom with a fluorine atom. It is a highly valuable molecule in industry, but is also a very dangerous chemical for biological systems.
