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.

3 gru 2023 · Hi, I was just wondering why BF3 is a Lewis Acid because boron is an exception to the octet rule and only forms a three bonds. Therefore, how can it be a Lewis acid and accept more electrons?
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.
It is technically produced by the reaction of B 2 O 3 with fluorspar and sulfuric acid: B 2 O 3 + 6HF → 2BF 3 + 3H 2 O. 76,77 BF 3 is an electron-deficient monomeric compound showing a trigonal planar structure with the D3h symmetry. It is a strong Lewis acid, which forms many one-to-one complexes. 78–80.
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:
