Melatonin (C13H16N2O2, CAS 73-31-4) — a free educational 3D molecular model for teachers and students, by MolGod.org. Each atom is labelled with its own engraved element symbol: no colour chart needed.
At its heart, Melatonin is built around two rings (one 5-membered and one 6-membered), fused along a shared edge, both aromatic. The model shows 34 bonds: 23 single, 1 double and 10 aromatic, drawn in Kekulé form. Hand the model round and let students tally the engraved atoms: 13 C + 16 H + 2 N + 2 O, 33 in total. Before any theory, let students hunt on the model for the amide group (-CO-N<) and the ether linkage (C-O-C).
