Why BF3 is a weak Lewis acid than BI3 while 'F' in BF3 is more electronegative?

Strong acids ionize fully in water to produce ions whereas weak acids donot ionize fully in water.
Boric acid behaves as a Lewis acid and accepts OH- ions from water.It doesnot dissociate to produce ions rather forms metaborate ion and in turn release ions.
Hence boric acid is considered a weak acid.

∙ 14y agoIt is due to the structure of BF3. B generally goes against the octet rule, due most likely to orbitals. Therefore BF3 exists and AlF3 does not.

What happenes in a Lewis acid-base reaction?
The Lewis base donates one or more pairs of electrons to the Lewis acid in order to form a compound with one or more dative bonds.
Which element is given first the more electronegative or less electronegative?
fluorine is most electronegative and cesium is least electronegative
Which is more electronegative?
Halogen elements
Definition of an acid not dependent of the solvent?
The most general definition of an acid relies on Lewis acid/base theory, which defines an acid as a substance (usually an atom on a substance) that can accept an electron pair from another group.For example, the proton H+ can accept a lone electron pair from OH- and is therefore an acid by the Lewis definition (it is also a Brønsted-Lowry acid as well). The hydrogens in the hydronium ion, H3O+ (a more accurate representation of the "lone" proton, which chemists often use only for convenience) are also Lewis acids by the same reasoning.Iron(III) chloride, FeCl3, is an example of a Lewis acid that does not fit under the Arrhenius or Brønsted-Lowry definitions - it can accept a lone pair from, say, a chloride ion. This is particularly useful in Friedel-Crafts alkylation and acylation reactions.
Why is the bond between N and H in amines a polar bond?
Nitrogen is more electronegative.
Which is the increasing acidity order of those Lewis acid BF3 BBr3 BI3 BCl3?
Increasing order of Lewis acidity BH3>BBR3>BCl3>BF3
Stronger acid trichloracetic acid or trifloracetic acid?
Trifluoroacetic acid by a bit as fluorine is more electronegative than chlorine.
Why is hydrofluoric acid is not a strong acid as other acids with halide ions?
Fluorine is highly electronegative, but does not easily release a proton into aqueous solution. Because of this, it is not as strong an acid as HCl, HBr, HI, etc., which more easily release a proton into solution. For Bronsted-Lowry acids, the more easily a substance dissociates into a proton (or multiple protons) and an electronegative moiety, the stronger an acid it is. For Lewis acids, stronger acids are substances that are stronger electron acceptors.
How does this amino acid gives power to the battery?
the acid strips the electrons from the metals so that they can flow to the more electronegative end
Which is more electronegative O or Se?
Oxygen is more electronegative than selenium.

Is oxygen more electronegative than sulfur?
Yes, oxygen is more electronegative than sulfur. This is because its electronegativity is about 3.44, while sulfur's is about 2.58.
