Silicon tetrabromide, also known as tetrabromosilane, is the inorganic compound with the formula SiBr 4. [1] This colorless liquid has a suffocating odor due to its tendency to hydrolyze with release of hydrogen bromide. [2] The general properties of silicon tetrabromide closely resemble those of the more commonly used silicon tetrachloride. [2]
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
In a tetrahedral molecular geometry, a central atom is located at the center with four substituents that are located at the corners of a tetrahedron.The bond angles are arccos(− 1 / 3 ) = 109.4712206...° ≈ 109.5° when all four substituents are the same, as in methane (CH 4) [1] [2] as well as its heavier analogues.
Silicon tetrafluoride or tetrafluorosilane is a chemical compound with the formula Si F 4. This colorless gas is notable for having a narrow liquid range: its boiling point is only 4 °C above its melting point.
Silicon tetraiodide is the chemical compound with the formula Si I 4. It is a tetrahedral molecule with Si-I bond lengths of 2.432(5) Å. [1] SiI 4 is a precursor to silicon amides of the formula Si(NR 2) 4 (R = alkyl). [2] It has also been of interest in the manufacture and etching of silicon in microelectronics.
The 3-center 4-electron (3c–4e) bond is a model used to explain bonding in certain hypervalent molecules such as tetratomic and hexatomic interhalogen compounds, sulfur tetrafluoride, the xenon fluorides, and the bifluoride ion.
The LDQ structure of the ground state of O 2 does not involve any electron pairs, in contrast with the Lewis structure of the molecule. Instead, the electrons are arranged as shown below. The LDQ structure of molecular oxygen in the ground state (3 Σ g − state). The oxygen nuclei are coloured red while the electrons are coloured either ...
Silicon tetrachloride or tetrachlorosilane is the inorganic compound with the formula SiCl 4. It is a colorless volatile liquid that fumes in air. It is used to produce high purity silicon and silica for commercial applications. It is a part of the chlorosilane family.
