  2. Bond length - Wikipedia

    en.wikipedia.org/wiki/Bond_length

    Shorter than average C–C bond distances are also possible: alkenes and alkynes have bond lengths of respectively 133 and 120 pm due to increased s-character of the sigma bond. In benzene all bonds have the same length: 139 pm. Carbon–carbon single bonds increased s-character is also notable in the central bond of diacetylene (137 pm) and ...

  3. Carbon–fluorine bond - Wikipedia

    en.wikipedia.org/wiki/Carbon–fluorine_bond

    The carbon–fluorine bond length is typically about 1.35 ångström (1.39 Å in fluoromethane). [1] It is shorter than any other carbon–halogen bond, and shorter than single carbon–nitrogen and carbon–oxygen bonds.

  5. Atomic spacing - Wikipedia

    en.wikipedia.org/wiki/Atomic_spacing

    In solid materials, the atomic spacing is described by the bond lengths of its atoms. In ordered solids, the atomic spacing between two bonded atoms is generally around a few ångströms (Å), which is on the order of 10 −10 meters (see Lattice constant ).

  7. Silicon monosulfide - Wikipedia

    en.wikipedia.org/wiki/Silicon_monosulfide

    Silicon monosulfide is a chemical compound of silicon and sulfur.The chemical formula is SiS. Molecular SiS has been detected at high temperature in the gas phase. [1] The gas phase molecule has an Si-S bondlength of 192.93 pm, this compares to the normal single bond length of 216 pm, [1] [2] and is shorter than the Si=S bond length of around 201 pm reported in an organosilanethione. [1]

  8. Triplet oxygen - Wikipedia

    en.wikipedia.org/wiki/Triplet_oxygen

    However, the alternative structure •O–O• is also inadequate, since it implies single bond character, while the experimentally determined bond length of 121 pm [6] is much shorter than the single bond in hydrogen peroxide (HO–OH) which has a length of 147.5 pm. [7] This indicates that triplet oxygen has a higher bond order.

  9. Thionyl tetrafluoride - Wikipedia

    en.wikipedia.org/wiki/Thionyl_tetrafluoride

    The shape of the molecule is a distorted trigonal bipyramid, with the oxygen found on the equator. 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.
