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
