Iodine Monofluoride
Iodine monofluoride is an interhalogen compound of iodine and fluorine with formula IF. It is a chocolate-brown solid that decomposes at 0 °C, disproportionation, disproportionating to elemental iodine and iodine pentafluoride: :5 IF → 2 I2 + IF5 However, its molecular properties can still be precisely determined by spectroscopy: the iodine-fluorine distance is 190.9 pm and the I−F bond dissociation energy is around 277 kJ mol−1. At 298 kelvin, K, its standard enthalpy change of formation is Δf''H''° = −95.4 kJ mol−1, and its Gibbs free energy is Δf''G''° = −117.6 kJ mol−1. It can be generated, albeit only fleetingly, by the reaction of the elements at −45 °C in trichlorofluoromethane, CCl3F: :I2 + F2 → 2 IF It can also be generated by the reaction of iodine with iodine trifluoride at −78 °C in CCl3F: :I2 + IF3 → 3 IF The reaction of iodine with silver(I) fluoride at 0 °C also yields io ...

Iodine Trifluoride
Iodine trifluoride is an interhalogen compound with the chemical formula IF3. It is a yellow solid which decomposes above −28 °C. It can be synthesised from the elements, but care must be taken to avoid the formation of IF5. Reactions F2 reacts with I2 to yield IF3 at −45 °C in CCl3F. Alternatively, at low temperatures, the fluorination reaction I2 + 3 XeF2 → 2IF3 + 3 Xe can be used. Not much is known about iodine trifluoride as it is so unstable. Structure The iodine atom of iodine trifluoride has five electron pairs, of which two are lone-pairs, and the molecule is T-shaped as predicted by VSEPR Theory Valence shell electron pair repulsion (VSEPR) theory ( , ) is a conceptual model, model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms. It is also named the Gill .... References {{Fluorine compounds Fluorides Interhalogen compounds Iodine compounds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iodine Pentafluoride
Iodine pentafluoride is an interhalogen compound with chemical formula IF5. It is one of the fluorides of iodine. It is a colorless liquid, although impure samples appear yellow. It is used as a fluorination reagent and even a solvent in specialized syntheses. Preparation 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. :I2 + 5 F2 → 2 IF5 Reactions IF5 reacts vigorously with water forming hydrofluoric acid and iodic acid: :IF5 + 3 H2O → HIO3 + 5 HF Upon treatment with fluorine, it converts to iodine heptafluoride: :IF5 + F2 → IF7 It has been used as a solvent for handling metal fluorides. For example, the reduction of osmium hexafluoride to osmium pentafluoride with iodine is conducted in a solution in iodine pentafluoride: :10 OsF6 + I2 → 10 OsF5 + 2 IF5 Primary amines react with iodi ...
