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]
In organic chemistry, planar, three-connected carbon centers that are trigonal planar are often described as having sp 2 hybridization. [2] [3] Nitrogen inversion is the distortion of pyramidal amines through a transition state that is trigonal planar. Pyramidalization is a distortion of this molecular shape towards a tetrahedral molecular ...
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 ]
Tetrafluorohydrazine was originally prepared from nitrogen trifluoride using a copper as a fluorine atom acceptor: [3] 2NF 3 + Cu → N 2 F 4 + CuF 2. A number of F-atom acceptors can be used, including carbon, other metals, and nitric oxide. These reactions exploit the relatively weak N-F bond in NF 3. [4]
A bond angle is the geometric angle between two adjacent bonds. Some common shapes of simple molecules include: Linear: In a linear model, atoms are connected in a straight line. The bond angles are set at 180°. For example, carbon dioxide and nitric oxide have a linear molecular shape.
In chemistry, a trigonal pyramid is a molecular geometry with one atom at the apex and three atoms at the corners of a trigonal base, resembling a tetrahedron (not to be confused with the tetrahedral geometry). When all three atoms at the corners are identical, the molecule belongs to point group C 3v.
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 ...
