Acrolein dimer (C6H8O2, CAS 100-73-2) — a free educational 3D molecular model for teachers and students, by MolGod.org. Every sphere shows which element it is through an engraved symbol, not a colour code.
At its heart, Acrolein dimer is built around one 6-membered ring. The model shows 16 bonds: 14 single and 2 double. Students work from the model back to the formula C6H8O2: the symbol count is 6 C + 8 H + 2 O, or 16 atoms all told. This molecule gives students these functional groups to identify: aldehyde group (-CHO), ether linkage (C-O-C) and carbon-carbon double bond (C=C). There is one stereocentre in Acrolein dimer; the configuration is not specified in this record, so students can work out what the R and S forms would look like. Students meeting chirality, enantiomers and CIP (R/S) rules, as well as the carbonyl group (C=O) for the first time can hold an example in their hands.
MolGod.org shares these models for free to make chemistry tangible in the classroom. Teachers: pass the model round at the start of the lesson, before showing any diagram.

A ball-and-stick model of Acrolein dimer 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: 197,044 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
Names in other languages: 3,4-Dihydro-2H-pyran-2-carboxaldehyd (de).
