Molecular Shapes Worksheet

Read each question carefully and provide clear, concise answers. Show all your work where applicable.

1. Which theory is used to predict the geometry of molecules based on the repulsion of electron pairs?

2. What is the molecular geometry of a molecule with two bonding pairs and zero lone pairs around the central atom?

1. The VSEPR theory states that electron pairs around a central atom will arrange themselves to minimize  .

2. A molecule with a tetrahedral electron geometry and one lone pair will have a   molecular geometry.

3. The bond angle in a perfectly linear molecule is   degrees.

1. Explain how the presence of lone pairs affects the molecular geometry of a molecule compared to a molecule with only bonding pairs.

2. Draw the Lewis structure for H₂O and predict its molecular geometry. Justify your answer.

1. All molecules with polar bonds are polar molecules.

2. The electron geometry and molecular geometry are always the same.

Refer to the diagram below to answer the following questions.

1. What is the molecular geometry of a molecule with 4 electron domains and 3 bonding domains?

2. Describe the bond angles for a trigonal bipyramidal molecular geometry.
