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. Every atom carries its engraved element symbol (C, H, O, N...), so no colour key is needed. Which rings can the class see in Vanillin? The answer is one aromatic 6-membered ring, joined up by 19 bonds altogether (12 single, 1 double and 6 aromatic, drawn in Kekulé form). Hand the model round and let students tally the engraved atoms: 8 C + 8 H + 3 O, 19 in total. This molecule gives…
