  2. Boron trifluoride - Wikipedia

    en.wikipedia.org/wiki/Boron_trifluoride

    The adduct with diethyl ether, boron trifluoride diethyl etherate, or just boron trifluoride etherate, (BF 3 ·O(CH 2 CH 3) 2) is a conveniently handled liquid and consequently is widely encountered as a laboratory source of BF 3. [16] Another common adduct is the adduct with dimethyl sulfide (BF 3 ·S(CH 3) 2), which can be handled as a neat ...

  3. Trigonal planar molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Trigonal_planar_molecular...

    Structure of boron trifluoride, an example of a molecule with trigonal planar geometry.. In chemistry, trigonal planar is a molecular geometry model with one atom at the center and three atoms at the corners of an equilateral triangle, called peripheral atoms, all in one plane. [1]

  4. Boron compounds - Wikipedia

    en.wikipedia.org/wiki/Boron_compounds

    The trihalides adopt a planar trigonal structure. These compounds are Lewis acids in that they readily form adducts with electron-pair donors, which are called Lewis bases. For example, fluoride (F −) and boron trifluoride (BF 3) combined to give the tetrafluoroborate anion, BF 4 −. Boron trifluoride is used in the petrochemical industry as ...

  5. Lewis acids and bases - Wikipedia

    en.wikipedia.org/wiki/Lewis_acids_and_bases

    Another example is boron trifluoride diethyl etherate, BF 3 ·Et 2 O. In a slightly different usage, the center dot is also used to represent hydrate coordination in various crystals, as in MgSO 4 ·7H 2 O for hydrated magnesium sulfate, irrespective of whether the water forms a dative bond with the metal.

  6. Fluorine compounds - Wikipedia

    en.wikipedia.org/wiki/Fluorine_compounds

    Boron trifluoride is a planar molecule. It has only six electrons around the central boron atom (and thus an incomplete octet), but it readily accepts a Lewis base, forming adducts with lone-pair-containing molecules or ions such as ammonia or another fluoride ion which can donate two more electrons to complete the octet. [79]

  7. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    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.

  8. Trigonal pyramidal molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Trigonal_pyramidal...

    In contrast, boron trifluoride is flat, adopting a trigonal planar geometry because the boron does not have a lone pair of electrons. In ammonia the trigonal pyramid undergoes rapid nitrogen inversion .

  9. Boron monofluoride - Wikipedia

    en.wikipedia.org/wiki/Boron_monofluoride

    Lewis dot diagram structures show three formal alternatives for describing bonding in boron monofluoride. BF is unusual in that the dipole moment is inverted with fluorine having a positive charge even though it is the more electronegative element. This is explained by the 2sp orbitals of boron being reoriented and having a higher electron density.
