Nitrogen trifluoride is the inorganic compound with the formula (NF 3).It is a colorless, non-flammable, toxic gas with a slightly musty odor.In contrast with ammonia, it is nonbasic.
In a tetrahedral molecular geometry, a central atom is located at the center with four substituents that are located at the corners of a tetrahedron. The bond angles are arccos (− 1 / 3 ) = 109.4712206...° ≈ 109.5° when all four substituents are the same, as in methane ( CH 4 ) [ 1 ] [ 2 ] as well as its heavier analogues .
Tetrafluoroammonium salts are prepared by oxidising nitrogen trifluoride with fluorine in the presence of a strong Lewis acid which acts as a fluoride ion acceptor. The original synthesis by Tolberg, Rewick, Stringham, and Hill in 1966 employs antimony pentafluoride as the Lewis acid: [5]
NF3 may refer to: Nitrogen trifluoride (NF 3), a colorless gas used as an etchant; Zukertort Opening, an opening move in chess (1. Nf3) This page was last edited on 3 ...
The methane molecule (CH 4) is tetrahedral because there are four pairs of electrons. The four hydrogen atoms are positioned at the vertices of a tetrahedron, and the bond angle is cos −1 (− 1 ⁄ 3) ≈ 109° 28′. [16] [17] This is referred to as an AX 4 type of molecule. As mentioned above, A represents the central atom and X represents ...
where: β > α are the two greatest valence angles of coordination center; θ = cos −1 (− 1 ⁄ 3) ≈ 109.5° is a tetrahedral angle. Extreme values of τ 4 and τ 4 ′ denote exactly the same geometries, however τ 4 ′ is always less or equal to τ 4 so the deviation from ideal tetrahedral geometry is more visible.
Thiazyl trifluoride is a chemical compound of nitrogen, sulfur, and fluorine, having the formula NSF 3.It exists as a stable, colourless gas, and is an important precursor to other sulfur-nitrogen-fluorine compounds. [2]
Walsh Diagram of an HAH molecule. Walsh diagrams, often called angular coordinate diagrams or correlation diagrams, are representations of calculated orbital binding energies of a molecule versus a distortion coordinate (bond angles), used for making quick predictions about the geometries of small molecules.
