Perfluorooctanesulfonic acid 3D Molecular Model — CAS 1763-23-1

Perfluorooctanesulfonic acid (C8HF17O3S, CAS 1763-23-1) — a free educational 3D molecular model for teachers and students, by MolGod.org. Instead of colour coding, every sphere carries its engraved element symbol.

An acyclic molecule to start with: Perfluorooctanesulfonic acid joins 30 atoms through 29 bonds (27 single and 2 double), and students will not find a ring. How many atoms can the class find? The engraved spheres give 8 C + 1 H + 17 F + 3 O + 1 S, so the answer should be 30. Where on the model can students see the sulfonic acid group (-SO3H) and the 17 C-F bonds? Let them search before you reveal the answer. Topics it supports in class: organohalogen compounds and carbon-halogen bonds. Where could this molecule form hydrogen bonds? The computed count is 2 acceptors and 1 donor.

Free for education: MolGod.org publishes engraved molecular models for teachers, students and schools. Teachers: pair it with the MolGod.org record to connect the 3D shape with identifiers and data.

A ball-and-stick model of Perfluorooctanesulfonic acid with each element symbol recessed into its atom sphere, generated by MolGod.org from a PubChem-computed 3D conformer (not an experimental crystal structure); atomic coordinates and connectivity are unchanged. STL mesh: 396,032 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
