Testosterone (C19H28O2, CAS 58-22-0) — a free educational 3D molecular model for teachers and students, by MolGod.org. Symbols are engraved into every atom, so students read atoms by symbol, not by colour. Which rings can the class see in Testosterone? The answer is four rings (one 5-membered and three 6-membered), with three pairs of rings fused along a shared edge, joined up by 52 bonds altogether (50 single and 2 double). How many atoms can the class find? The engraved spheres give 19 C + 28 H + 2 O, so the answer should be 49. Before any theory, let students hunt on the model for the ketone group (C=O), the hydroxyl group (-OH) and the carbon-carbon double bond (C=C).
