Oxygen fluoride
Chemical compounds of oxygen and fluorine
Oxygen fluorides are a group of compounds consisting of oxygen and fluorine. These compounds are notable for their reactivity and are used in various chemical applications. The most common oxygen fluorides are oxygen difluoride (OF2), dioxygen difluoride (O2F2), and trioxygen difluoride (O3F2).
Oxygen Difluoride[edit | edit source]
Oxygen difluoride (OF2) is a chemical compound with a bent molecular geometry. It is a pale yellow gas at room temperature and is known for its strong oxidizing properties. Oxygen difluoride is used in various industrial applications, including as an oxidizer in rocket propellants.
Properties[edit | edit source]
Oxygen difluoride is a highly reactive compound. It reacts with water to form hydrogen fluoride and oxygen. The compound is also known to react with many metals and nonmetals, often forming fluorides and oxides.
Preparation[edit | edit source]
Oxygen difluoride can be prepared by the reaction of fluorine with a dilute solution of sodium hydroxide:
- 2 F2 + 2 NaOH → OF2 + 2 NaF + H2O
Dioxygen Difluoride[edit | edit source]
Dioxygen difluoride (O2F2) is a compound with a very unusual structure and extreme reactivity. It is a reddish-orange solid at low temperatures and decomposes explosively at temperatures above −160 °C.
Properties[edit | edit source]
Dioxygen difluoride is known for its ability to oxidize almost any material, including noble gases like xenon. It is one of the most powerful oxidizing agents known.
Preparation[edit | edit source]
Dioxygen difluoride is typically prepared by the reaction of fluorine with oxygen at low temperatures:
- O2 + F2 → O2F2
Trioxygen Difluoride[edit | edit source]
Trioxygen difluoride (O3F2) is a less common oxygen fluoride. It is a powerful oxidizing agent and is used in specialized chemical syntheses.
Properties[edit | edit source]
Trioxygen difluoride is a highly reactive compound, capable of oxidizing a wide range of substances. It is less stable than oxygen difluoride and is typically handled with care in controlled environments.
Preparation[edit | edit source]
The preparation of trioxygen difluoride involves the reaction of ozone with fluorine under controlled conditions:
- O3 + F2 → O3F2
