5. Construct a model of dihydrogen monoxide and dihydrogen sulfide.

a. Draw the structural formula based off of your model. Include any unshared

pairs. Note: these are not represented in your model.

b. What is the shape of the molecule?

c. What is the bond type (polar or nonpolar)?

d. What is the molecule type (polar or nonpolar)?

6. Construct a model of carbon dioxide.

a. Draw the structural formula based off of your model. Include any unshared

pairs. Note: these are not represented in your model.

b. What is the shape of the molecule?

c. What is the bond type (polar or nonpolar)?

d. What is the molecule type (polar or nonpolar)?

7. Construct a model of ammonia and ammonium.

a. Draw the structural formula for each based off of your model. Include any unshared

pairs. Note: these are not represented in your model.

b. What is the shape of each molecule?

c. What is the bond type for each(polar or nonpolar)?

d. What is the molecule type for each (polar or nonpolar)?

8. Construct a model for methane.

a. Draw the structural formula for each based off of your model. Include any unshared

pairs. Note: these are not represented in your model.

b. What is the shape of each molecule?

c. What is the bond type for each(polar or nonpolar)?

d. What is the molecule type for each (polar or nonpolar)?

9. Construct a model for carbon tetrachloride.

a. Draw the structural formula for each based off of your model. Include any unshared

pairs. Note: these are not represented in your model.

b. What is the shape of each molecule?

c. What is the bond type for each(polar or nonpolar)?

10. Construct a model of Chloroethane (CH 3 Cl).

a. Draw the structural formula based off of your model. Include any unshared

pairs. Note: these are not represented in your model.

b. What is the shape of the molecule?

c. What is the bond type (polar or nonpolar)?

d. What is the molecule type (polar or nonpolar)?

Conclusion Questions:

1. How can molecular polarity be determined on the basis of molecular shape?

2. Both water and carbon dioxide are triatomic molecules. Explain why one of these is polar

and the other is nonpolar. Use illustrations to help explain your answer. (If you completely

understand this question you probably have this concept down.)
