  2. Nitrogen trifluoride - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_trifluoride

    Nitrogen trifluoride concentration at several latitudes since 2015. [22] NF3 measured by the Advanced Global Atmospheric Gases Experiment in the lower atmosphere (troposphere) at stations around the world. Abundances are given as pollution free monthly mean mole fractions in parts-per-trillion.

  3. Pnictogen - Wikipedia

    en.wikipedia.org/wiki/Pnictogen

    Nitrogen trifluoride is the only stable nitrogen trihalide, with nitrogen trichloride, nitrogen tribromide, and nitrogen triiodide being explosive—nitrogen triiodide being so shock-sensitive that the touch of a feather detonates it (the last three actually feature nitrogen in the −3 oxidation state).

  4. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    Angular: Angular molecules (also called bent or V-shaped) have a non-linear shape. For example, water (H 2 O), which has an angle of about 105°. A water molecule has two pairs of bonded electrons and two unshared lone pairs. Tetrahedral: Tetra-signifies four, and -hedral relates to a face of a solid, so "tetrahedral" literally means "having ...

  5. Trigonal pyramidal molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Trigonal_pyramidal...

    When all three atoms at the corners are identical, the molecule belongs to point group C 3v. Some molecules and ions with trigonal pyramidal geometry are the pnictogen hydrides (XH 3), xenon trioxide (XeO 3), the chlorate ion, ClO − 3, and the sulfite ion, SO 2− 3.

  6. Nitrogen fluoride - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_fluoride

    Nitrogen fluorides are compounds of chemical elements nitrogen and fluorine. Many different nitrogen fluorides are known: ... Nitrogen trifluoride, NF 3; Nitrogen ...

  7. T-shaped molecular geometry - Wikipedia

    en.wikipedia.org/wiki/T-shaped_molecular_geometry

    The T-shaped geometry is related to the trigonal bipyramidal molecular geometry for AX 5 molecules with three equatorial and two axial ligands. In an AX 3 E 2 molecule, the two lone pairs occupy two equatorial positions, and the three ligand atoms occupy the two axial positions as well as one equatorial position. The three atoms bond at 90 ...

  8. Tetrafluorohydrazine - Wikipedia

    en.wikipedia.org/wiki/Tetrafluorohydrazine

    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]

  9. Trigonal planar molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Trigonal_planar_molecular...

    Structure of boron trifluoride, an example of a molecule with trigonal planar geometry.. In chemistry, trigonal planar is a molecular geometry model with one atom at the center and three atoms at the corners of an equilateral triangle, called peripheral atoms, all in one plane. [1]
