What is a Brønsted-Lowry acid but not an Arrhenius acid A.PO43- B.HCl C.NH4plus D.BF3?
D. BF3 - While BF3 can donate a proton and therefore act as a Brønsted-Lowry acid, it does not generate H+ ions in water and therefore is not considered an Arrhenius acid.
Is BF3 an acid?
Yes, BF3 (boron trifluoride) is an acid. It is a Lewis acid, which means it is an electron acceptor and can react with Lewis bases to form coordination complexes.
Is BF3 a Arrhenius acid?
No, BF3 is not an Arrhenius acid. It is a Lewis acid because it can accept a pair of electrons from a Lewis base to form a coordinate covalent bond.
Which is the increasing acidity order of those Lewis acid BF3 BBr3 BI3 BCl3?
The increasing acidity order of these Lewis acids is: BCl3 < BBr3 < BI3 < BF3. This trend is due to the decreasing ability of the halogen to stabilize the negative charge on the Lewis acid, leading to increased acidity as you move from BCl3 to BF3.
What happens when BF3 is reacted with ammonia?
When BF3 is reacted with ammonia, the ammonia coordinates with the boron atom in BF3 to form an adduct called ammonia borane or NH3-BF3. This adduct is a stable compound that is used in various chemical reactions and hydrogen storage applications.

What is the type of intermolecular force present in BF3?
The primary type of intermolecular force present in BF3 (boron trifluoride) is London dispersion forces, which are weak forces arising from temporary dipoles that occur in all molecules. While BF3 is a nonpolar molecule due to its symmetrical trigonal planar shape, these dispersion forces can still influence the interactions between BF3 molecules. Additionally, because BF3 can act as a Lewis acid, it can engage in dipole-dipole interactions with polar molecules or Lewis bases in certain reactions, but these are not considered the primary intermolecular forces in pure BF3.
Is BF3 a stable compound?
Yes, boron trifluoride (BF3) is considered a stable compound under standard conditions. However, it is an electron-deficient molecule and acts as a Lewis acid, readily accepting electron pairs from Lewis bases. Despite its stability, BF3 can react with various compounds, particularly those containing lone pairs of electrons, forming adducts.
What happens when BF3 is reacted with ammonia?
When BF3 is reacted with ammonia, the ammonia coordinates with the boron atom in BF3 to form an adduct called ammonia borane or NH3-BF3. This adduct is a stable compound that is used in various chemical reactions and hydrogen storage applications.
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.
Is BF3 a resonance structure?
Boron trifluoride (BF3) is not a resonance structure; it is a stable molecule with a trigonal planar geometry. In BF3, boron has only six electrons in its valence shell, resulting in an incomplete octet, which is characteristic of certain compounds involving elements from the third period and beyond. While BF3 does not have resonance structures, it can act as a Lewis acid by accepting a pair of electrons.
Why BF3 is a weaker acid than BCl3?
BF3 is a weaker acid than BCl3 because fluorine is more electronegative than chlorine, leading to a stronger B-F bond compared to the B-Cl bond. The stronger B-F bond makes it harder for BF3 to donate a proton, resulting in lower acidity. Conversely, the B-Cl bond in BCl3 is weaker due to the lower electronegativity of chlorine, making it easier for BCl3 to donate a proton, hence it is a stronger acid.
What is a Lewis acid?
A Lewis acid accepts an electron pair from a base. ---APEX--
