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. Hand the model round and let students tally the engraved atoms: 12 C + 12 H + 2 N + 1 O, 27 in total. Spot-the-group challeng…
