Cinnamaldehyde 3D Molecular Model — CAS 104-55-2

Cinnamaldehyde (C9H8O, CAS 104-55-2) — a free educational 3D molecular model for teachers and students, by MolGod.org. Every sphere shows which element it is through an engraved symbol, not a colour code. In Cinnamaldehyde the ring system sets the overall shape: one aromatic 6-membered ring. Altogether 18 bonds hold the model together (10 single, 2 double and 6 aromatic, drawn in Kekulé form). How many atoms can the class find? The engraved spheres give 9 C + 8 H + 1 O, so the answer should be…
