The Lewis structure of XeF 2 shows two bonding pairs and three lone pairs of electrons around the Xe atom: XeF 6: We place three lone pairs of electrons around each F atom, accounting for 36 electrons. mol−1. This means that the Lewis dot structure for C2H6 must account for 14 valence electrons, either through bonding between atoms, or through lone pairs. For the CH3OH Lewis structure there are a total of 20 valence electrons available. The electrons are unequally shared, with the oxygen atom spending more time with electrons than the hydrogen atoms. Chloroform is widely used for the manufacturing of refrigerant gases like Freon refrigerant R-22. Geometrical shape: The shape of a molecule is also an important factor to check the polarity of a molecule. Each Hydrogen has a single bond, so it has two valence electrons. This induces a permanent dipole across the molecule with a partial positive charge on the hydrogen atom and a partial negative charge on the chlorine atoms.
