Is KrF2 Polar or Nonpolar? - Science Coverage

Krypton difluoride is primarily a powerful oxidising and fluorinating agent: for example, it can oxidise gold to its highest-known oxidation state, +5. It is more powerful even than elemental fluorine due to the even lower bond energy of Kr–F compared to F–F, with a redox potential of +3.5 V for the KrF2/Kr couple, making it the most powerful known oxidising agent, though KrF 4 could be even stronger: WebJan 18, 2024 · Step #2: Select the center atom. While selecting the atom, always put the least electronegative atom at the center. Here in the KrF2 molecule, if we compare the krypton atom (Kr) and fluorine atom (F), then the krypton is less electronegative than fluorine. So, krypton should be placed in the center and the remaining 2 fluorine atoms will …
