General Description
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 highest electropositivity of all non-radioactive elements and fluorine has the highest electronegativity of all elements.
