In this section we will take a look at some common molecules in 3-Dimensions using the Chemis3D Java Applet. The molecules shown in the applet are described below. They are written with their 'chemical formula' which tells the number of atom types in each molecule.

Water H₂0

Methane CH₄

Benzene C ₆H₁₂

Butane C₄H₁₀

Aspirin C₉H₈O₄

Caffeine C₈H₁₀N₄O₂

DNA (DNA is a long chain polymer) What type of atoms is DNA composed of (Hint: use the color code shown below?

Exercise: In the applet below, see if you can verify the chemical formula's for each molecule using the color code below.

Color Code: Hydrogen -White; Carbon -Gray; Oxygen-Red; Nitrogen; Blue; Phosphorus -Orange -To rotate in 3-D hold left mouse button down and move cursor in window. To zoom use [Shift] left-click.
