Serotonin 3D Molecular Model — CAS 50-67-9

Serotonin (C10H12N2O, CAS 50-67-9) — a free educational 3D molecular model for teachers and students, by MolGod.org. Whatever the filament colour, each atom reads clearly thanks to its engraved symbol. Start with the ring system: Serotonin has two rings (one 5-membered and one 6-membered), fused along a shared edge, both aromatic; in total the model carries 26 bonds (16 single and 10 aromatic, drawn in Kekulé form). Quick starter: ask students to count the engraved symbols (10 C + 12 H + 2 N + 1 O) and check that they add up to 25 atoms and the formula C10H12N2O. Ask the class to locate the phenolic hydroxyl group (Ar-OH) and the primary amino group (-NH2) and name each one.
