Polar Bond: A polar bond is a type of bond that is formed due to the electronegativity difference between the atoms. Classify each diatomic molecule as polar or nonpolar. In these cases, molecules that are classified nonpolar because of their shape becomes polar because the polarity of different bonds doesn't cancel out equally so there is a net polarity. As the bond dipoles is not arranged symmetrically, it is not a polar molecule. F2 and HBr are a pair of a polar and nonpolar molecule, so the IMFs they have are induced dipole because of the polar nature of HBr. nonpolar polar nonpolar polar. The two main classes of molecules are polar molecules and nonpolar molecules.Some molecules are clearly polar or nonpolar, while others fall somewhere on the spectrum between two classes.

Nonpolar compounds either have no polar bonds or contain symmetrical polar bonds. Start studying Polar or Non-Polar. Diatomic molecules composed of two of the same elements are always non-polar. In polar molecules, there exist two poles in a molecule (negative and positive). d. F2 is a polar molecule because the F-F bond is polar. However, because of the TETRAHEDRAL arrangement of the C – F bonds, the bond moments cancel exactly, so that CF4 has a ZERO total permanent dipole moment. I want to know the nature of XeF2 in both molecular and solid forms. So F has more electrons than H making it polar. However Xe-F bond is polar because the electronegativity of Xe and F is different but the polarity of both Xe-F bonds gets canceled by each other resulting in a nonpolar XeF2 molecule.
