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. See more 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 … See more Unlike the aluminium and gallium trihalides, the boron trihalides are all monomeric. They undergo rapid halide exchange reactions: BF3 + BCl3 → … See more 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 they … See more 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 See more 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 … See more Organic chemistry Boron trifluoride is most importantly used as a reagent in organic synthesis, typically as a See more • List of highly toxic gases See more WebBoron trifluoride is a colourless gas and has a pungent odour. It is toxic. It is soluble in water. Its melting and boiling points are -127 ˚C and -100 ˚C, respectively. It is an …
