  2. Thionyl tetrafluoride - Wikipedia

    en.wikipedia.org/wiki/Thionyl_tetrafluoride

    The atoms on the equator have shorter bond lengths than the fluorine atoms on the axis. In the gas-phase, the sulfur oxygen bond is 1.409Å. A S−F bond on the axis has length 1.596Å and the S−F bond on the equator has length 1.539Å. The angle between the equatorial fluorine atoms is 112.8°. The angle between axial fluorine and oxygen is ...

  3. 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.

  4. Fluorination by sulfur tetrafluoride - Wikipedia

    en.wikipedia.org/wiki/Fluorination_by_sulfur...

    Fluorination by sulfur tetrafluoride produces organofluorine compounds from oxygen-containing organic functional groups using sulfur tetrafluoride. The reaction has broad scope, and SF 4 is an inexpensive reagent. It is however hazardous gas whose handling requires specialized apparatus.

  5. Orbital hybridisation - Wikipedia

    en.wikipedia.org/wiki/Orbital_hybridisation

    Chemist Linus Pauling first developed the hybridisation theory in 1931 to explain the structure of simple molecules such as methane (CH 4) using atomic orbitals. [2] Pauling pointed out that a carbon atom forms four bonds by using one s and three p orbitals, so that "it might be inferred" that a carbon atom would form three bonds at right angles (using p orbitals) and a fourth weaker bond ...

  6. Tetrahedral molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Tetrahedral_molecular_geometry

    In the gas phase, a single water molecule has an oxygen atom surrounded by two hydrogens and two lone pairs, and the H 2 O geometry is simply described as bent without considering the nonbonding lone pairs. [citation needed] However, in liquid water or in ice, the lone pairs form hydrogen bonds with neighboring water molecules. The most common ...

  7. Difluorodisulfanedifluoride - Wikipedia

    en.wikipedia.org/wiki/Difluorodisulfanedifluoride

    FSSF 3 is stable as a solid, as a liquid below -74 °C and dissolved in other sulfur fluoride liquids. [8] This is in contrast to SF 2 which is only stable as a dilute gas. [8] Infrared vibration bands for FSSF 3 are at 810, 678, 530, 725, and 618(S-S) cm −1. [8]

  8. List of states of matter - Wikipedia

    en.wikipedia.org/wiki/List_of_states_of_matter

    Liquid: A mostly non-compressible fluid. Able to conform to the shape of its container but retains a (nearly) constant volume independent of pressure. Gas: A compressible fluid. Not only will a gas take the shape of its container but it will also expand to fill the container. Mesomorphic states: States of matter intermediate between solid and ...

  9. Dispersion (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Dispersion_(chemistry)

    Dispersion is a process by which (in the case of solid dispersing in a liquid) agglomerated particles are separated from each other, and a new interface between the inner surface of the liquid dispersion medium and the surface of the dispersed particles is generated. This process is facilitated by molecular diffusion and convection. [4]
