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). Quick starter: ask students to count the engraved symbols (2 C + 4 H + 2 Cl) and check that they add up to 8 atoms and the formula C2H4Cl2. 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.
