This molecular model-building lab is designed to help you develop a mental model that gives a three-dimensional image to two-dimensional Lewis structures that you draw on paper.
1. Select any 2 from each of the following sections. Sketch the Lewis structure, then build the model of the molecule. Identify the shape and bond angles of each,
2. Start with ClO1-, then make ClO21-, ClO31-, and ClO41-. Identify the shape of each. Write the name of each ion. Sketch each one first.
3. Build 3 of the following pairs from Experiment 14: sketch first
C6H12 & C6H14
C4H9OH & C5H11OH
C2H4(OH)2 & C3H5(OH)3
4. Make a model of your acid from Experiment 13. Sketch first and be sure to write the name of your acid
5. Draw the Lewis structure for each of the following expanded octet molecules. Then make a model of any 4 of them. Give the shape of the molecule and the type of hybridization around the central atom.
Results & Discussion:
Describe the effect of the number of lone pairs and bonds on the shape and bond angle of the molecule and relate the shapes of the molecules you built to their expected polarity. Look back in Experiment 14 to see how the polarity of the solutes tested compare to their shape and types of bonds.
Answer the application questions from Experiment 13 that were omitted when you did that experiment. Tape the sheet with the structures onto the left-hand page opposite the page where you answer these questions.
