OF2 boiling point

The oxygen difluoride boiling point is -144.750 C.

OF2 state at room temperature

OF2 molecules exist in a gaseous state at room temperature.

OF2 covalent bond

Oxygen difluoride is a covalent compound because the two fluorine atoms are covalently bonded with a central atom.

OF2 covalent radius

The covalent radii of oxygen and fluorine in oxygen difluoride molecules are 0.74Å and 60 picometres. As the covalent radii of molecules are not found we can find the covalent radius of subsequent atoms separately.

OF2 electron configurations

Electrons are arranged into the atomic orbitals of an element. This arrangement is known as electronic configuration. Let us discuss the electronic configuration of OF2.

In OF2 the central metal atom is oxygen. So, its outermost electronic configuration is 1s2 2s2 2P4, and the fluorine atom electronic configuration is 1s2 2s2 2P5.

OF2 oxidation state

The central atom, oxygen, is in a +2 oxidation state in oxygen difluoride. Each of the 2 fluorine atoms is in -1 in oxygen difluoride.

OF2 acidity/alkaline

Oxygen difluoride is a covalent neutral molecule. So, Oxygen difluoride is not a typical acid or a base, nor does it react with sodium hydroxide. It is so inert.

Is OF2 odorless

Oxygen difluoride is a colorless gas with a vigorous peculiar odor.

Is OF2 paramagnetic

Para magnetic substances are those having unpaired electrons in their outermost electronic configuration. Let us see OF2 magnetic behavior.

Oxygen difluoride is diamagnetic because it contains paired electrons in the outermost electronic orbital.

OF2 hydrates

OF2 slowly reacts with water to form hydrofluoric acid.

OF 2 (aq) + H 2(l) → 2 HF (aq) + O

OF2 crystal structure

  • Oxygen difluoride possesses a covalent crystal structure. According to VSEPR theory, it adopts a bent structure. The point group symbol of the oxygen difluoride is C2V.
  • Oxygen difluoride structure resembles the structure of water molecules.

OF2 Structure

OF2 polarity and Conductivity

  • Oxygen difluoride is a polar molecule because the dipole moment of O-F is not canceled out, giving a polar structure.
  • Oxygen difluoride may not conduct electricity because of its slow dissociation in water.

OF2 reaction with acid

Due to the shielding of oxygen by two fluorine atoms, oxygen difluoride does not undergo any reaction with acids.

OF2 reaction with base

OF2 does not undergo any reaction with the bases as it is thermodynamically more stable.

OF2reaction with oxide

  • Oxygen difluoride can oxidize sulfur dioxide to sulfur trioxide and diatomic fluorine molecules.

OF2 + SO2 → SO3 + F2

  • But in the presence of ultraviolet radiation, oxygen difluoride yields sulfuryl fluoride (SO2F2) and pyro sulfuryl fluoride(S2O5F2).  

OF2 + 2 SO2 → S2O5F2

OF2 reaction with the metal

OF2 can react with many metals to give fluorides and oxides.OF2 can also react with nonmetals like phosphorous to yield PF5 and POF3. The scandium oxyfluoride free radical, OScF2, is produced by the reaction of laser-ablated Sc atoms with OF2 in solid argon.

Sc + OF2 = OScF2

OF2 +laser ablated metal = OYF2+OLaF2

Conclusion

Oxygen difluoride can blow out in contact with water. It is a strong fluorinating agent. Prolonged exposure to high heat may cause rupturing.
