Aspirin (C9H8O4, CAS 50-78-2) — a free educational 3D molecular model for teachers and students, by MolGod.org. Instead of colour coding, every sphere carries its engraved element symbol.
Look at the skeleton first: Aspirin contains one aromatic 6-membered ring, and students can trace 21 bonds (13 single, 2 double and 6 aromatic, drawn in Kekulé form). Students work from the model back to the formula C9H8O4: the symbol count is 9 C + 8 H + 4 O, or 21 atoms all told. Before any theory, let students hunt on the model for the carboxylic acid group (-COOH) and the ester group (-COO-).
