8-Hydroxyquinoline 3D Model — CAS 148-24-3

8-Hydroxyquinoline (C9H7NO, CAS 148-24-3) — 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. Look at the skeleton first: 8-Hydroxyquinoline contains two 6-membered rings, fused along a shared edge, both aromatic, and students can trace 19 bonds (8 single and 11 aromatic, drawn in Kekulé form). Hand the model round and let students tally the engraved atoms: 9 C + 7 H + 1 N + 1 O,…
