Silane (Silicane) is an inorganic compound with chemical formula SiH 4. It is a colorless, pyrophoric gas with a sharp, repulsive, pungent smell, somewhat similar to that of acetic acid . [ 6 ] Silane is of practical interest as a precursor to elemental silicon .
Chemical structure of disilane, which is structurally similar to ethane. Silanes are saturated chemical compounds with the empirical formula Si x H y. They are hydrosilanes, a class of compounds that includes compounds with Si−H and other Si−X bonds. All contain tetrahedral silicon and terminal hydrides.
Polysilicon hydrides are polymers containing only silicon and hydrogen. They have the formula () where 0.2 ≤ n ≤ 2.5 and x is the number of monomer units. The polysilicon hydrides are generally colorless or pale-yellow/ocher powders that are easily hydrolyzed and ignite readily in air.
Hydrosilanes are tetravalent silicon compounds containing one or more Si-H bond. The parent hydrosilane is silane (SiH 4). Commonly, hydrosilane refers to organosilicon derivatives. Examples include phenylsilane (PhSiH 3) and triethoxysilane ((C 2 H 5 O) 3 SiH). Polymers and oligomers terminated with hydrosilanes are resins that are used to ...
The ordered structure forms the β- phase, whereas the higher temperature and more symmetrical disordered structure is called α- phase. The β- phase is about 15% more compact than the α-phase. [8] The silanide ion has C 3v symmetry. The silicon to hydrogen bond length is 1.52 Å and the H-Si-H bond angle is 92.2°, not far off a right angle. [8]
This series has the chemical formula X 2 H 6.Ethane is commonly found alongside methane in natural gas.The other hydrides of the chemical formula X 2 H 6 are less stable than the corresponding tetrahydrides XH 4, and they are more and more less stable as X goes from carbon (ethane C 2 H 6 is stable) down to lead (or flerovium) in the periodic table (diplumbane Pb 2 H 6 is unknown [1]).
[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.
Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another.
