  1. ChemistryBondingMolecular Polarity Do Now: Take out HW to check CALCULATORS NOT REQUIRED PERIODIC TABLES REQUIRED

  2. A polar bond tends to make the entire molecule “polar” areas of “difference” of electronegativity HCl has polar bonds, thus is a polar molecule. A molecule that has two poles is called a dipole, like HCl Polarity is shown on a diagram with a polarity arrow+----> positive end negative end Polar molecules

  3. The effect of polar bonds on the polarity of the entire molecule depends on the molecule shape carbon dioxide has two polar bonds, and is linear = nonpolar molecule! The polarities pull evenly, making the molecule nonpolar, but the bonds polar. Polar molecules

  4. The effect of polar bonds on the polarity of the entire molecule depends on the molecule shape water has two polar bonds and a bent shape; the highly electronegative oxygen pulls the e- away from H = very polar! Polar molecules

  5. The rule of thumb to follow is that if identical polar bonds are placed evenly around the central atom, the molecule is nonpolar. If the polar bonds are unequally placed, the molecule is polar. Polar molecules

  6. Polarity

  7. Polar or nonpolar? H2 H2O NH3 CH4 CO2 CO Polar molecules
