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
