4,4'-Diaminodiphenyl Ether — CAS 101-80-4

4,4'-Diaminodiphenyl Ether (C12H12N2O, CAS 101-80-4) — a free educational 3D molecular model for teachers and students, by MolGod.org. Every atom carries its engraved element symbol (C, H, O, N...), so no colour key is needed. At its heart, 4,4'-Diaminodiphenyl Ether is built around two 6-membered rings, both aromatic. The model shows 28 bonds: 16 single and 12 aromatic. Counting task: 12 C + 12 H + 2 N + 1 O gives 27 engraved spheres; can the class rebuild the formula C12H12N2O from the model alone? Ask the class to locate the ether linkage (C-O-C) and the two primary amino groups (-NH2) and name each one.
