Iodine pentafluoride forming nitriles after hydrolysis with water: Iodine pentafluoride is available as a "Special Gas" for flooding into the atmosphere of the escape shuttle in the terminal sequence of 1979 film Alien. Iodine pentafluoride Iodine pentafluoride is an interhalogen compound with chemical formula IF. It is a fluoride of iodine. It is a colorless or yellow liquid with a density of 3.250 g cm. It was first synthesized by Henri Moissan in 1891 by burning solid iodine in fluorine gas. This exothermic reaction is still used to produce iodine pentafluoride, although the reaction conditions have been improved. Iodine pentafluoride is a
