L-menthol 3D Molecular Model — CAS 2216-51-5

L-menthol (C10H20O, CAS 2216-51-5) — a free educational 3D molecular model for teachers and students, by MolGod.org. Element symbols are cut into each atom sphere: a self-labelled teaching aid.

Look at the skeleton first: L-menthol contains one 6-membered ring, and students can trace 31 bonds (all of them single). Hand the model round and let students tally the engraved atoms: 10 C + 20 H + 1 O, 31 in total. On the printed model, students can point to the hydroxyl group (-OH). L-menthol has three stereocentres (R, S, R): a hands-on way to practise finding them and checking the CIP assignment. A good fit for lessons on chirality, enantiomers and CIP (R/S) rules, as well as on alcohols and hydrogen bonding.

MolGod.org publishes its molecular models free of charge for teachers and students. Teachers: the engraved symbols let students work with the model without a separate key.

A ball-and-stick model of L-menthol 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: 329,522 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.

Names in other languages: Menthol (de); menthol (fr); mentolo (it); mentol (pl); 薄荷醇 (zh).
