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 b…
