Acetic acid (C2H4O2, CAS 64-19-7) — a free educational 3D molecular model for teachers and students, by MolGod.org. Symbols are engraved into every atom, so students read atoms by symbol, not by colour.
Lay Acetic acid on the desk and search for a ring: there isn't one. Its 8 atoms hang together through 7 bonds (6 single and 1 double). Counting task: 2 C + 4 H + 2 O gives 8 engraved spheres; can the class rebuild the formula C2H4O2 from the model alone? On the printed model, students can point to the carboxylic acid group (-COOH).
