No discussion of molecular structure would be complete without illustrations of Hydrocarbons. Besides their own somewhat interesting structures they also provide links to  Sugars , Biological Molecules ,and Diamonds Silicon and Semiconductors . Not much stereo or 3D chemistry is involved with hydrocarbons but they suggest it.
