It is far less reactive than the other nitrogen trihalides nitrogen trichloride, nitrogen tribromide, and nitrogen triiodide, all of which are explosive. Alone among the nitrogen trihalides it has a negative enthalpy of formation. It is prepared in modern times both by direct reaction of ammonia and fluorine and by a variation of Ruff's method. [6]
The attractive force draws molecules closer together and gives a real gas a tendency to occupy a smaller volume than an ideal gas. Which interaction is more important depends on temperature and pressure (see compressibility factor). In a gas, the distances between molecules are generally large, so intermolecular forces have only a small effect.
Atmospheric concentration of SF 6, NF 3, and several widely used HFCs and PFCs between years 1978 and 2015 (right graph).Note the logarithmic scale. The most common F-gases are hydrofluorocarbons (HFCs), which contain hydrogen, fluorine, and carbon.
Nitrogen fluorides are compounds of chemical elements nitrogen and fluorine. Many different nitrogen fluorides are known: ... Nitrogen trifluoride, NF 3; Nitrogen ...
Trifluoramine oxide was first discovered in 1966 independently by two different groups. One way to produce it was by an electric discharge in a mixture of oxygen on nitrogen trifluoride. Another even less yielding method is by reacting noble metal fluorides (IrF 6 or PtF 6) with nitric oxide. [1]
The trifluorooxonium cation is a hypothetical positively charged polyatomic ion with chemical formula O F + 3.It is structurally equivalent to the hydronium ion where the hydrogen atoms surrounding the central oxygen atom have been replaced by fluorine, and is isoelectronic with nitrogen trifluoride.
The reaction of nitrogen trifluoride with fluorine and boron trifluoride at 800 °C yields the tetrafluoroborate salt: [6] NF 3 + F 2 + BF 3 → NF 4 BF 4. NF + 4 salts can also be prepared by fluorination of NF 3 with krypton difluoride (KrF 2) and fluorides of the form MF n, where M is Sb, Nb, Pt, Ti, or B. For example, reaction of NF 3 with ...
Nitrogen trifluoride (NF 3, first prepared in 1928) is a colourless and odourless gas that is thermodynamically stable, and most readily produced by the electrolysis of molten ammonium fluoride dissolved in anhydrous hydrogen fluoride. Like carbon tetrafluoride, it is not at all reactive and is stable in water or dilute aqueous acids or alkalis.
