Fenadiazole 3D Molecular Model — CAS 1008-65-7

Fenadiazole (C8H6N2O2, CAS 1008-65-7) — a free educational 3D molecular model for teachers and students, by MolGod.org. Every atom carries its engraved element symbol, so no colour key is needed. Start with the ring system: Fenadiazole has two rings (one 5-membered and one 6-membered), both aromatic; in total the model carries 19 bonds (8 single and 11 aromatic, drawn in Kekulé form). Counting task: 8 C + 6 H + 2 N + 2 O gives 18 engraved spheres; can the class rebuild the formula C8H6N2O2 from the model alone? Team task: with the model in hand, each group marks the phenolic hydroxyl group (Ar-OH) and the two pyridine-type ring nitrogens, then writes down what they found.
