BF₃ (boron trifluoride) is polar due to its trigonal planar geometry and the presence of a significant difference in electronegativity between boron and fluorine, which creates a net dipole moment. However, SO₂ (sulfur dioxide) is polar because of its bent molecular shape; the dipole moments from the sulfur-oxygen bonds do not cancel each other out, making it polar. In contrast, if one were to consider SO₂ being nonpolar, it would be inaccurate; SO₂ is indeed polar due to its molecular geometry.
Nonpolar
It is non-polar
Polar molecules reacts with polar molecules and non-polar molecules react with non-polar molecules.
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.
polar
SO2 is a polar molecule because the sulfur atom has a lone pair of electrons, causing an asymmetrical distribution of charge within the molecule. This creates a dipole moment and makes SO2 a polar molecule.
BF3 is a nonpolar molecule because the boron atom is surrounded by three fluorine atoms arranged in a trigonal planar geometry, creating a symmetric distribution of charge that cancels out any dipole moment.
Polar covalent. The difference in electronegtivity is insufficient for an ionic bond
SO2 is a polar molecule because it has a bent molecular geometry and a region of different electronegativities between sulfur and oxygen atoms. This leads to an uneven distribution of charge and creates a dipole moment.
No. The individual bonds are polar, but BF3 is trigonal planar so the overall molecule is not polar.
AlCl3 is the only non-polar molecule in the list provided. The other molecules (CO, SO2, and NO) have polar covalent bonds due to differences in electronegativity between the atoms involved, making them polar molecules. AlCl3 has a symmetrical arrangement of polar covalent bonds, resulting in a non-polar molecule overall.
Among the molecules listed, HF and NF3 have polar bonds due to differences in electronegativity between the bonded atoms. ICl3, SF4, and BF3 are nonpolar because the bond dipoles cancel out in these molecules, resulting in a symmetrical distribution of charge.
BF3 has a nonpolar covalent bond because the electronegativity difference between boron and fluorine is not significant enough to create a polar covalent bond. In a nonpolar covalent bond, electrons are shared equally between the atoms involved.
SO2 is a polar compound.So it dissolves well.
While the sulfur-oxygen bond in SO2 is polar due to the difference in electronegativity between sulfur and oxygen, the overall molecule is considered polar because of its bent shape which results in an uneven distribution of charge. Therefore, SO2 is a polar molecule.
Yes BF3 is soluble in water.Although its VSEPR shape is trigonal planar, which is supposed to be non-polar, the fluorine atoms, to which the Boron atom is attached, are able to form hydrogen bonds with water molecules. Therefore, BF3 is soluble in water.
Boron trifluoride (BF3) does not mix with water (H2O) because BF3 is a nonpolar molecule, whereas water is a polar molecule. Polar molecules are attracted to other polar molecules due to their opposite charges, whereas nonpolar molecules are not attracted to polar molecules. This difference in polarity prevents the two substances from mixing.
