1,2-Dichloroethane 3D Model — CAS 107-06-2

1,2-Dichloroethane (C2H4Cl2, CAS 107-06-2) — a free educational 3D molecular model for teachers and students, by MolGod.org. Instead of colour coding, every sphere carries its engraved element symbol.

1,2-Dichloroethane has no rings at all: its 8 atoms form an open chain held together by 7 bonds (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? Spot-the-group challenge: can students find the two C-Cl bonds? Use it when you teach organohalogen compounds and carbon-halogen bonds. Its closest structural relatives in the MolGod.org collection are Dichloromethane (CAS 75-09-2) and 1-Chloro-4-iodobutane (CAS 10297-05-9); printing them side by side makes a quick compare-and-contrast exercise.

MolGod.org shares these models for free to make chemistry tangible in the classroom. Teachers: print one per group and let students check the structure against the formula.

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.
