Lewis Dot Structures (Multiple Choice)

This page presents a few exercises to help you draw Lewis Dot Structures. When you press "New Problem", a molecular formula will be shown below. Try to draw the Lewis Structure for this molecule without looking at the choices. When you think you have the correct structure, click "Show Choices" and a window with possible structures will appear. Select a structure with a radio button and your response will be graded and your total score updated. Click "New Problem" for the next molecule. Reloading the page will clear the score (if you want to start over).

Note that being able to recognize the correct structure is easier than drawing one from scratch. You should be able to do both...
