3,3'-Dichloro-4,4'-Diaminodiphenylmethane (C13H12Cl2N2, CAS 101-14-4) — a free educational 3D molecular model for teachers and students, by MolGod.org. Whatever the filament colour, each atom reads clearly thanks to its engraved symbol. At its heart, 3,3'-Dichloro-4,4'-Diaminodiphenylmethane is built around two 6-membered rings, both aromatic. The model shows 30 bonds: 18 single and 12 aromatic, drawn in Kekulé form. How many atoms can the class find? The engraved spheres give 13 C + 12 H + 2 Cl + 2 N, so the answer should be 29. On the printed model, students can point to the two primary amino groups (-NH2) and the two C-Cl bonds.
