Ibuprofen, (+-) (C13H18O2, CAS 15687-27-1) — a free educational 3D molecular model for teachers and students, by MolGod.org. Read the atoms directly: each sphere bears an engraved element symbol. Let the group sketch what they see in Ibuprofen, (+-), namely one aromatic 6-membered ring; afterwards they compare the sketch with the 33 bonds on the model (26 single, 1 double and 6 aromatic, drawn in Kekulé form). Counting task: 13 C + 18 H + 2 O gives 33 engraved spheres; can the class rebuild the formula C13H18O2 from the model alone? Where on the model can students see the carboxylic acid group (-COOH)? Let them search before you reveal the answer.
