Unformatted text preview: electronegativity For our purposes use the definitions in the chart. The most polar bond determines the polarity of a molecule (i.e. if a compound contains one non-polar, and one polar bond the molecule, as a whole, is considered to be polar) % ionic character EN polarity 0 10 0 0.5 non-polar 10 50 0.5 1.7 polar (covalent) 50 100 1.7 + ionic A B C D E F G Molecule Lewis structure Draw shape. Indicate bond dipoles EN of bonds Polarity of bonds (ignore shape) Symmetrical molecule? (i.e. all pulls cancel out) Polarity of molecule 1. NH 3 3.1 2.1 = 1.0 polar No polar 2. N 2 3. HBr H Br 4. OCl 2 5. SF 6 H 6. SO 2 7. SiCl 4 8. CF 2 Cl 2 C-F: C-Cl: 9. XeF 4 Note: the EN for Xe is 2.6 10. C 2 H 4 C-C: C-H: Q which binary (two element) compound would have the greatest EN?
