Answer Questions

9. What is a polar bond? What is a nonpolar bond?
Questions to Ask
What is a polar bond? What is a nonpolar bond?
Look at question 10… answer out loud
Compare CO2 and H2O on board
Have students draw the Lewis structures

10. Three Degrees of Polarity
Non Polar Covalent
Equal sharing of electrons
Typically is symmetrical

11. Three Degrees of Polarity
Polar Covalent
Unequal sharing of electrons between the atoms
Typically is asymmetrical

12. Three Degrees of Polarity
Ionic
The more electronegative atom wins and seizes the bonding electrons (transfer) from the weaker atom

13. Polar or NonPolar?
Nonpolar

14. Polar or NonPolar?
Polar

15. Polar or Nonpolar?
WATER
Polar

16. Water vs. Acetone
Water
Polar
Acetone
Nonpolar

17. Styrofoam Made from polystyrene Nonpolar

18. Like Dissolves Like
Polar compounds tend to dissolve in polar solvents (like water)
Non-polar compounds tend to dissolve in non-polar solvents
**Know the saying – “Like dissolves Like” 
