Vanillin 3D Molecular Model — CAS 121-33-5

Vanillin (C8H8O3, CAS 121-33-5) — a free educational 3D molecular model for teachers and students, by MolGod.org. Each atom is labelled with its own engraved element symbol: no colour chart needed. Look at the skeleton first: Vanillin contains one aromatic 6-membered ring, and students can trace 19 bonds (12 single, 1 double and 6 aromatic). Hand the model round and let students tally the engraved atoms: 8 C + 8 H + 3 O, 19 in total. On the printed model, students can point to the aldehyde grou…
