Lesson 29 Polar Molecules

  • Polar Molecules have an overall charge separation 
  • Unsymmetrical molecules are usually polar 
  • Molecular dipoles are the result of unequal sharing of a molecule 
Polar and Non-Polar Molecules


Non Polar Molecule

PREDICTING POLARITY
  • If a molecule is symmetrical the pull on e is usually balanced 
  • Molecules can be un-symmetrical in two ways 
              - different atoms
              - different number of atoms
