What is selenium tetraflouride?

Selenium tetrafluoride (SeF4) is a chemical compound consisting of one selenium atom and four fluorine atoms. It is a colorless gas that reacts vigorously with water and organic materials. It has a pungent odor and is highly toxic and corrosive to the respiratory system and skin.

SeF4 is used in organic synthesis as a fluorinating agent and in the manufacturing of various chemicals, including pesticides and pharmaceuticals. It is also used in the semiconductor industry for the production of chips and other electronic components.

SeF4 is a covalent compound with a trigonal bipyramidal geometry. It has a boiling point of -38.2 °C and a melting point of -78.85 °C. SeF4 readily reacts with water to form selenious acid (H2SeO3) and hydrofluoric acid (HF), which are highly corrosive and toxic.

SeF4 must be handled with extreme care due to its toxic and corrosive properties. It should be stored in a cool, dry place in a tightly sealed container away from heat sources and incompatible materials. Personal protective equipment, including gloves, protective clothing, and a respirator, should be worn when handling SeF4.
