Experimental iron-silicon phase diagram. Binary compounds of silicon are binary chemical compounds containing silicon and one other chemical element. [1] Technically the term silicide is reserved for any compounds containing silicon bonded to a more electropositive element.
Like other chlorosilanes or silanes, silicon tetrachloride reacts readily with water: . SiCl 4 + 2 H 2 O → SiO 2 + 4 HCl. The reaction can be noticed on exposure of the liquid to air, as SiCl 4 vapour produces fumes as it reacts with moisture to give a cloud-like aerosol of silica and hydrochloric acid. [6]
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.
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.
This compound is produced by treating silicon-copper mixture with iodine: [3] Si + I 2 → SiI 4. It reacts quickly with water and moisture in the air. It can also be made on a large scale by reaction of silicon or silicon carbide with iodine on heating to about 200 °C.
The Hammett equation predicts the equilibrium constant or reaction rate of a reaction from a substituent constant and a reaction type constant. The Edwards equation relates the nucleophilic power to polarisability and basicity. The Marcus equation is an example of a quadratic free-energy relationship (QFER). [citation needed]
