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 thr…
