4,4'-Diaminodiphenyl Ether 3D Molecular Model — 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. Whatever the filament colour, each atom reads clearly thanks to its engraved symbol.

Let the group sketch what they see in 4,4'-Diaminodiphenyl Ether, namely two 6-membered rings, both aromatic; afterwards they compare the sketch with the 28 bonds on the model (16 single and 12 aromatic). Use the engraved letters like a register: call out each element and tick it off until the class reaches 12 C + 12 H + 2 N + 1 O (27 atoms altogether). Spot-the-group challenge: can students find the ether linkage (C-O-C) and the two primary amino groups (-NH2)? Teachers covering aromaticity and delocalised electrons, as well as amines and basicity will find it a concrete example. Pair it with p,p'-Oxybis(benzenesulfonyl hydrazide) (CAS 80-51-3) from the same collection to compare closely related structures.

MolGod.org publishes its molecular models free of charge for teachers and students. Teachers: use it as a hands-on starter before drawing the structural formula on the board.

A ball-and-stick model of 4,4'-Diaminodiphenyl Ether with each element symbol recessed into its atom sphere, generated by MolGod.org from a PubChem-computed 3D conformer (not an experimental crystal structure); atomic coordinates and connectivity are unchanged. STL mesh: 359,500 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
