Boron trifluoride is a versatile Lewis acid that forms adducts with such Lewis bases as fluoride and ethers: CsF + BF 3 → Cs[BF 4] O(CH 2 CH 3) 2 + BF 3 → BF 3 ·O(CH 2 CH 3) 2. Tetrafluoroborate salts are commonly employed as non-coordinating anions.
Easily forms coordination complexes with molecules having at least one unshared pair of electrons; forms solid complex with nitric acid (HNO3.2BF3); polymerizes unsaturated molecules O'Neil, M.J. (ed.).

16 sty 2023 · BF 3 is a planar molecule because it does not have a lone pair, which makes it have a trigonal planar geometry. BF 3 is considered a Lewis acid because it accepts electrons at its empty p orbital. Examples of reactivity of the empty p orbital. The most common reactions with involving BF 3 is to form complexes with ethers. figure 4. Other ...
29 lis 2015 · If BF 3 stripped an H atom off a water molecule, it would technically leave OH-in the solution, and actually raise the pH instead. BF 3 is a Lewis acid. Why would it raise the pH?
In the BF 3 affinity scale, Lewis bases' BF3 affinities are equal to the negative enthalpy change for formation of a solution phase adduct between the base and gaseous BF 3. The reaction is:
I'm trying to build a molecular orbital diagram for BF 3 and I'm running into problems with irreducible representations on the F side. 2s for B has an irreducible representation of A1. 2p for B has an irreducible representation of E' and A''2. 2s for F considered non bonding.
