  2. Sulfur tetrafluoride - Wikipedia

    en.wikipedia.org/wiki/Sulfur_tetrafluoride

    It is a colorless corrosive gas that releases dangerous hydrogen fluoride gas upon exposure to water or moisture. Sulfur tetrafluoride is a useful reagent for the preparation of organofluorine compounds, [3] some of which are important in the pharmaceutical and specialty chemical industries.

  3. Thionyl tetrafluoride - Wikipedia

    en.wikipedia.org/wiki/Thionyl_tetrafluoride

    Thionyl tetrafluoride, also known as sulfur tetrafluoride oxide, is an inorganic compound with the formula S O F 4.It is a colorless gas.. The shape of the molecule is a distorted trigonal bipyramid, with the oxygen found on the equator.

  4. Silicon tetrafluoride - Wikipedia

    en.wikipedia.org/wiki/Silicon_tetrafluoride

    This colorless gas is notable for having a narrow liquid range: its boiling point is only 4 °C above its melting point. It was first prepared in 1771 by Carl Wilhelm Scheele by dissolving silica in hydrofluoric acid, [5] and later synthesized by John Davy in 1812. [6] It is a tetrahedral molecule and is corrosive. [7]

  5. Bent's rule - Wikipedia

    en.wikipedia.org/wiki/Bent's_rule

    Shape of water molecule showing that the real bond angle 104.5° deviates from the ideal sp 3 angle of 109.5°. In chemistry, Bent's rule describes and explains the relationship between the orbital hybridization and the electronegativities of substituents. [1] [2] The rule was stated by Henry A. Bent as follows: [2]

  6. Isovalent hybridization - Wikipedia

    en.wikipedia.org/wiki/Isovalent_hybridization

    In chemistry, isovalent or second order hybridization is an extension of orbital hybridization, the mixing of atomic orbitals into hybrid orbitals which can form chemical bonds, to include fractional numbers of atomic orbitals of each type (s, p, d). It allows for a quantitative depiction of bond formation when the molecular geometry deviates ...

  7. Sulfuryl fluoride - Wikipedia

    en.wikipedia.org/wiki/Sulfuryl_fluoride

    Sulfuryl fluoride (also spelled sulphuryl fluoride) is an inorganic compound with the formula SO 2 F 2.It is an easily condensed gas and has properties more similar to sulfur hexafluoride than sulfuryl chloride, being resistant to hydrolysis even up to 150 °C. [3]

  8. Molecular diffusion - Wikipedia

    en.wikipedia.org/wiki/Molecular_diffusion

    Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles.

  9. Hypervalent molecule - Wikipedia

    en.wikipedia.org/wiki/Hypervalent_molecule

    Using the language of orbital hybridization, the bonds of molecules like PF 5 and SF 6 were said to be constructed from sp 3 d n orbitals on the central atom. Langmuir, on the other hand, upheld the dominance of the octet rule and preferred the use of ionic bonds to account for hypervalence without violating the rule (e.g. " SF 2+
