Perfluorooctanesulfonic acid — CAS 1763-23-1

Perfluorooctanesulfonic acid (C8HF17O3S, CAS 1763-23-1) — 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. There is not a single ring in Perfluorooctanesulfonic acid; 30 atoms are linked by 29 bonds in an open chain (27 single and 2 double). Hand the model round and let students tally the engraved atoms: 8 C + 1 H + 17 F + 3 O + 1 S, 30 in total. Functional groups to find on the model: sulfonic acid group (-SO3H) and 17 C-F bonds.
