    en.wikipedia.org/wiki/Diborane(4)

    Diborane(4) is a transient inorganic compound with the chemical formula B 2 H 4.Stable derivatives are known. Diborane(4) has been produced by abstraction of two hydrogen atoms from diborane(6) using atomic fluorine and detected by photoionization mass spectrometry. [1]

    en.wikipedia.org/wiki/Styx_rule

    The styx rule, also known as Lipscomb's styx rule, can be used to calculate the structures of boranes.It was developed by William Lipscomb in 1954. [1] The rule defines boranes to have four types of bonds besides the terminal B-H bonds: [2]

  4. Boranes - Wikipedia

    en.wikipedia.org/wiki/Boranes

    The development of the chemistry of boranes led to innovations in synthetic methods as well as structure and bonding. First, new synthetic techniques were required to handle diborane and many of its derivatives, which are both pyrophoric and volatile.

    [4] [5] An extended version of this model is used to describe the whole class of hypervalent molecules such as phosphorus pentafluoride and sulfur hexafluoride as well as multi-center π-bonding such as ozone and sulfur trioxide. There are also molecules such as diborane (B 2 H 6) and dialane (Al 2 H 6) which have three-center two-electron bond ...

    [4] [5] B 2 Cl 4, however, adopts a planar geometry when crystalized but favors the perpendicular geometry (D 2d symmetry) in the gas phase. [4] [5] Computations of the relative stability of the two conformers indicate that the D 2d geometry is ~2 kcal/mol lower in energy; the planar geometry in the solid phase is thought to be due to packing ...

    A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
