7.3 Example: Building cyclohexane

Cyclohexane in its chair configuration has a structure which seems quite complicated to generate, but it can easily be built using VIEWMOL's molecule builder. First, start VIEWMOL without any parameter on the command line and press Cancel in the file selection box which pops up. You should now have an empty window on your screen. Press the right mouse button within this window and select Molecule/New molecule ... from the pop-up menu. The molecule editor will open up. We start building cyclohexane by building one of the tetrahedra: To continue building cyclohexane we have to remember that the torsion angles among the carbon atoms alternate between gauche and -gauche which can be determined easily by looking at the Newman projection:
