Boron trifluoride is a versatile Lewis acid that forms adducts with such Lewis bases as fluoride and ethers : CsF + BF 3 → CsBF 4. O (C 2 H 5) 2 + BF 3 → BF 3 ·O (C 2 H 5) 2. Tetrafluoroborate salts are commonly employed as non-coordinating anions. Zobacz więcej Boron trifluoride is the inorganic compound with the formula BF3. This pungent, colourless, and toxic gas forms white fumes in moist air. It is a useful Lewis acid and a versatile building block for other boron compounds. Zobacz więcej BF3 is manufactured by the reaction of boron oxides with hydrogen fluoride: B2O3 + 6 HF → 2 BF3 + 3 H2O Typically the HF is produced in situ from sulfuric acid and fluorite (CaF2). Approximately 2300-4500 tonnes of boron trifluoride are … Zobacz więcej Organic chemistry Boron trifluoride is most importantly used as a reagent in organic synthesis, typically as a Lewis acid. Examples include: • Zobacz więcej The geometry of a molecule of BF3 is trigonal planar. Its D3h symmetry conforms with the prediction of VSEPR theory. The molecule has no dipole moment by virtue of its high symmetry. The molecule is isoelectronic with the carbonate anion, CO2−3. Zobacz więcej Anhydrous boron trifluoride has a boiling point of −100.3 °C and a critical temperature of −12.3 °C, so that it can be stored as a … Zobacz więcej Unlike the aluminium and gallium trihalides, the boron trihalides are all monomeric. They undergo rapid halide exchange … Zobacz więcej Boron trifluoride was discovered in 1808 by Joseph Louis Gay-Lussac and Louis Jacques Thénard, who were trying to isolate "fluoric acid" (i.e., hydrofluoric acid) by combining calcium fluoride with vitrified boric acid. The resulting vapours failed to etch glass, so … Zobacz więcej Witryna1 dzień temu · Boron Trifluoride (BF3) is an inorganic compound as it lacks a carbon atom or C-H bond in the molecule. Manufactured from the reaction of boron oxides and hydrogen fluoride, the chemical compound BF3 has a pungent smell and is colorless in nature. The compound behaves differently in different states of matter.
