Computer Exercise Description/Model Kit Overview

Click on worksheet to view the worksheet you should use to submit your answers. Write the formulas and answer the questions about each of the molecules on the worksheet.

Rotating the Molecules

Ethylamine:

In addition to the two static views of the molecules you also have the opportunity to rotate each of the molecules. Consider the sample molecule, CH3CH2NH2, shown at the left. To rotate the molecule you will need to click on ethylamine just above the image of the molecule, but please read the rest of this section before using the highlighted link.

After left-clicking on the above link, the molecule will appear in a new window. You may next left-click on either walk or spin to manipulate the molecule.

If the molecule ever disappears from the screen you will first need to right-click anywhere on the screen. Next, left-click on ViewPoints. Finally, left-click on Entry View. Following these steps will return the molecule to its original viewpoint.

Once you have finished rotating the molecule you can return to the exercise by clicking on the Back icon at the top of the window.

Model Kit Description
You should build models for the first four molecules. Use Views 1 and 2 of the molecule on the screen as your guide for building each of the models. The color of the atoms on the screen will be approximately the same as the color of the spheres you will use. You will use the short gray links in the model kit to form the bonds between the atoms.
