Is BF3 polar or nonpolar?

Question:- Is BF3 polar or nonpolar?

Answer: Boron trifluoride (BF₃) is nonpolar.

Like in the case of hydrogen chloride the molecule is nonpolar even though the bonds within it, between the boron and fluorines, are polar. This is a result of its molecular shape and the symmetry of the same molecule. BF3 has around the central boron atom three fluorine atoms that are similarly arranged at 120° from one another. Each B-F bond is polar because boron has a lower electronegativity than fluorine; however, the dipole moments of all the polar covalent bonds are cancelled out, thus making the molecule nonpolar. This is because as we realize the dipole moments of the three B-F bonds are canceled with each other as a result of the geometry of the Molecule. Thus, the net dipole moment of BF3 is zero and hence BF3 is non-polar. Moreover, this property is significant in the dynamism of this chemical in different chemical reactions as well as an application in Lewis acid in organic synthesis.
