In this game-like activity, you need to click on the correct atoms in the benzene molecules (the corners of the hexagons) to place the substituents in the proper positions for each xylene isomer. You should be able to figure out which combination of corners to click based on the directions below. This type of activity is more fun than just looking at the picture of the structures, allows the student to test placement on different corners by using the reset button, and is more effective at reinforcing the lesson than a static page.
