Iodine pentafluoride is an interhalogen compound with chemical formula IF 5. 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. [3]
[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.
Iodosyl pentafluoride is an inorganic compound of iodine, fluorine, ... Reaction of iodine heptafluoride with silicon dioxide: [3] [4] 2 IF 7 + SiO 2 → 2 IOF 5 + SiF 4.
Liquid iodine trichloride conducts electricity, possibly indicating dissociation to ICl + 2 and ICl − 4 ions. [9] Iodine pentafluoride (IF 5), a colourless, volatile liquid, is the most thermodynamically stable iodine fluoride, and can be made by reacting iodine with fluorine gas at room temperature. It is a fluorinating agent, but is mild ...
It is a chocolate-brown solid that decomposes at 0 °C, [1] disproportionating to elemental iodine and iodine pentafluoride: 5 IF → 2 I 2 + IF 5. 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.
The bond energy is significantly weaker than those of Cl 2 or Br 2 molecules and similar to the easily cleaved oxygen–oxygen bonds of peroxides or nitrogen–nitrogen bonds of hydrazines. [8] The covalent radius of fluorine of about 71 picometers found in F 2 molecules is significantly larger than that in other compounds because of this weak ...
In chemistry, an interhalogen compound is a molecule which contains two or more different halogen atoms (fluorine, chlorine, bromine, iodine, or astatine) and no atoms of elements from any other group. Most interhalogen compounds known are binary (composed of only two distinct elements).
All have the sodium chloride (rock salt) structure and are soluble in water and even some alcohols. [1] Because the fluoride anion is highly basic, many alkali metal fluorides form bifluorides with the formula MHF 2. Sodium and potassium bifluorides are significant to the chemical industry. [2]
