Check the post here to know about the SF6 molecular geometry and how to draw lewis structure of SF6. If there is an odd number of lone pairs of electrons around the central atom, the molecule is polar. a. BeCl2 b. SeF6 c. BF3 d. PF5 e. CF4. It is non-polar because the arrangement of C-Cl bonds in molecule is perfectly symmetrical. The easiest way to determine if a molecule is polar or nonpolar is to draw its Lewis Structure and, if necessary, check its molecular geometry. According to Fajan's rule, smaller the size of atom higher will be polarizing capacity and so the covalent character will be larger.
