Norepinephrine (C8H11NO3, CAS 51-41-2) — 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.
Start with the ring system: Norepinephrine has one aromatic 6-membered ring; in total the model carries 23 bonds (17 single and 6 aromatic, drawn in Kekulé form). How many atoms can the class find? The engraved spheres give 8 C + 11 H + 1 N + 3 O, so the answer should be 23. Ask students to locate one stereocentre in Norepinephrine and work out the R/S label by hand; the record gives R.
