Define the following terms:

Ball-and-stick model         Protein                           

VESPR theory                  Hydrogen bonds              

Bond angle                       Linear

Dipole                             Tetrahedral                    

Polar molecule                  Pyramidal

Nonpolar molecule           

 

Short answer questions: (answer these questions)

1) What do the letters VESPR stand for.  Explain what the theory says and how is it used?

 

2) Explain why silicon tetrafluoride has a square structural formula but tetrahedral arrangement in space.

 

3) Compare the bond lengths of single, double, and triple bonds.  Explain why the effect occurs.

 

4) Describe and explain the trend in bond length in atoms within a column of the periodic table.

 

5) Describe the role of polarity in large molecules.  Give an example.

 

6) Explain water is such an important substance and why life on Earth might be different if water were a linear molecule.

 

7) Describe the shapes and bond angles of certain molecules given.
