Reactions H + F2 and F + H2 are known to generate vibrationally excited HF, resulting in a significant amount of HF(n > 0) during the H2-F2 – Combustion is present. Vibrationally excited H2 can also be generated as a result of the V-V energy transfer reaction between HF(n = 1) and H2, (R5).
F2 + H2O → F2O + H.
…and fluorine react to form hydrogen fluoride, which contains HF molecules. The hydrogen and fluorine atoms are linked by a pair of electrons, with one electron contributed by the hydrogen atom and one by the fluorine atom.
When hydrogen sulfide (H2S) reacts with fluorine (F2), sulfur hexafluoride (SF6) is formed.
Fluorine reacts violently with water forming hydrogen fluoride and oxygen.
Structure and chemical properties of Hydrogen fluoride
Hydrogen fluoride is formed by covalent bonding (electron sharing) between a hydrogen atom and a fluorine atom. Hydrogen contains an electron, and fluorine needs an electron to become stable, so the bond forms easily when the two elements interact.
In the oxidation reaction, electrons are lost, causing them to be oxidized, while in the reduction reaction, electrons are gained, causing them to be reduced. In this case, H2 is oxidized while F2 is reduced.
The reaction is exothermic.
Another example of a redox reaction is the formation of hydrogen fluoride. We can break down the reaction to analyze the oxidation and reduction of reactants. The hydrogen is oxidized and gives up two electrons, so each hydrogen becomes positive. The two electrons are gained by fluorine, which is reduced.
