8-Hydroxyquinoline 3D Molecular 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. No legend required: the element symbol is engraved on each atom.

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). A five-minute warm-up: read the symbol on every sphere and write down the totals (9 C + 7 H + 1 N + 1 O = 18 atoms). On the printed model, students can point to the phenolic hydroxyl group (Ar-OH) and the pyridine-type ring nitrogen. It makes aromaticity and delocalised electrons, fused ring systems, heteroaromatic rings (nitrogen inside an aromatic ring), as well as phenols and hydrogen bonding easier to see. Worth printing alongside it: 2,2':6',2''-Terpyridine (CAS 1148-79-4) and 6-Aminoquinoline (CAS 580-15-4), structurally the nearest in the collection.

MolGod.org shares these models for free to make chemistry tangible in the classroom. Teachers: let students set the model beside a skeletal formula and list what the drawing omits.

A ball-and-stick model of 8-Hydroxyquinoline with each element symbol recessed into its atom sphere, generated by MolGod.org from a PubChem-computed 3D conformer (not an experimental crystal structure); atomic coordinates and connectivity are unchanged. STL mesh: 251,112 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
