Theophylline (C7H8N4O2, CAS 58-55-9) — a free educational 3D molecular model for teachers and students, by MolGod.org. Every atom carries its engraved element symbol (C, H, O, N...), so no colour key is needed.
Which rings can the class see in Theophylline? The answer is two rings (one 5-membered and one 6-membered), fused along a shared edge, one of them aromatic, joined up by 22 bonds altogether (15 single, 3 double and 4 aromatic). Hand the model round and let students tally the engraved atoms: 7 C + 8 H + 4 N + 2 O, 21 in total. Ask the class to locate the pyridine-type ring nitrogen and name each one.
