  2. Sulfur hexafluoride - Wikipedia

    en.wikipedia.org/wiki/Sulfur_hexafluoride

    6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. [citation needed] Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents.

  3. Hexafluorophosphate - Wikipedia

    en.wikipedia.org/wiki/Hexafluorophosphate

    Practical uses of the hexafluorophosphate ion typically exploit one or more of the following properties: that it is a non-coordinating anion; that hexafluorophosphate compounds are typically soluble in organic solvents, particularly polar ones, but have low solubility in aqueous solution; or, that it has a high degree of stability, including ...

  4. Octahedral molecular geometry - Wikipedia

    When an anionic ligand replaces a coordinated water molecule the reaction is called an anation. The reverse reaction, water replacing an anionic ligand, is called aquation. For example, the [CoCl(NH 3) 5] 2+ slowly yields [Co(NH 3) 5 (H 2 O)] 3+ in water, especially in the presence of acid or base. Addition of concentrated HCl converts the aquo ...

  5. Hexafluorosilicic acid - Wikipedia

    en.wikipedia.org/wiki/Hexafluorosilicic_acid

    Hexafluorosilicic acid is produced commercially from fluoride-containing minerals that also contain silicates. Specifically, apatite and fluorapatite are treated with sulfuric acid to give phosphoric acid, a precursor to several water-soluble fertilizers.

  6. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths , bond angles , torsional angles and any other geometrical parameters that determine the position of each atom.

  7. VSEPR theory - Wikipedia

    In effect, they considered nitrogen dioxide as an AX 2 E 0.5 molecule, with a geometry intermediate between NO + 2 and NO − 2. Similarly, chlorine dioxide (ClO 2) is an AX 2 E 1.5 molecule, with a geometry intermediate between ClO + 2 and ClO − 2. [citation needed] Finally, the methyl radical (CH 3) is predicted to be trigonal pyramidal ...

  8. Sulfur tetrafluoride - Wikipedia

    en.wikipedia.org/wiki/Sulfur_tetrafluoride

    In organic synthesis, SF 4 is used to convert COH and C=O groups into CF and CF 2 groups, respectively. [10] The efficiency of these conversions are highly variable. In the laboratory, the use of SF 4 has been superseded by the safer and more easily handled diethylaminosulfur trifluoride , (C 2 H 5 ) 2 NSF 3 , "DAST": [ 11 ] This reagent is ...

  9. Tungsten hexafluoride - Wikipedia

    en.wikipedia.org/wiki/Tungsten_hexafluoride

    Tungsten(VI) fluoride, also known as tungsten hexafluoride, is an inorganic compound with the formula W F 6.It is a toxic, corrosive, colorless gas, with a density of about 13 kg/m 3 (22 lb/cu yd) (roughly 11 times heavier than air).
