1,2-Dichloroethane (C2H4Cl2, CAS 107-06-2) — 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 1,2-Dichloroethane; 8 atoms are linked by 7 bonds in an open chain (all of them single). Counting task: 2 C + 4 H + 2 Cl gives 8 engraved spheres; can the class rebuild the formula C2H4Cl2 from the model alone? On the printed model, students can point to the two C-Cl bonds. A good fit for lessons on organohalogen compounds and carbon-halogen bonds. Want a comparison? The most similar structures in the MolGod.org collection are Dichloromethane (CAS 75-09-2) and 1-Chloro-4-iodobutane (CAS 10297-05-9).
This model is part of the free MolGod.org collection of engraved molecules for education. Teachers: pair it with the MolGod.org record to connect the 3D shape with identifiers and data.

A ball-and-stick model of 1,2-Dichloroethane 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: 99,132 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
Names in other languages: 1,2-Dichlorethan (de); 1,2-dichloroéthane (fr); 1,2-dicloroetano (it); 1,2-dichloorethaan (nl); 1,2-dichloroetan (pl); 1,2-二氯乙烷 (zh).
