Oxygen difluoride is a chemical compound with the formula OF 2. As predicted by VSEPR theory, the molecule adopts a bent molecular geometry. [citation needed] It is a strong oxidizer and has attracted attention in rocketry for this reason. [5] With a boiling point of −144.75 °C, OF 2 is the most volatile (isolable) triatomic compound. [6]
Oxygen difluoride. A common preparative method involves fluorination of sodium hydroxide: 2 F 2 + 2 NaOH → OF 2 + 2 NaF + H 2 O. OF 2 is a colorless gas at room temperature and a yellow liquid below 128 K. Oxygen difluoride has an irritating odor and is poisonous. [3] It reacts quantitatively with aqueous haloacids to give free halogens:

Tetraoxygen difluoride is an inorganic chemical compound of oxygen, belonging to the family of oxygen fluorides. It consists of two O 2 F units bound together with a weak O-O bond, and is the dimer of the O 2 F radical.
The rest of the Earth's crust is formed also of oxygen compounds, most importantly calcium carbonate (in limestone) and silicates (in feldspars). Water-soluble silicates in the form of Na 4 SiO 4, Na 2 SiO 3, and Na 2 Si 2 O 5 are used as detergents and adhesives. [6] Peroxides retain some of oxygen's original molecular structure ((− O-O −).

Certain atoms, such as oxygen, will almost always set their two (or more) covalent bonds in non-collinear directions due to their electron configuration. Water (H 2 O) is an example of a bent molecule, as well as its analogues. The bond angle between the two hydrogen atoms is approximately 104.45°. [1]
Thus, as substituents become more electronegative, the bond angle of the molecule should decrease. Dimethyl ether, methanol, water and oxygen difluoride follow this trend as expected (as is shown in the table above). Two methyl groups are the substituents attached to the central oxygen in diethyl ether.
