4-Nitroaniline (C6H6N2O2, CAS 100-01-6) — a free educational 3D molecular model for teachers and students, by MolGod.org. Each atom is labelled with its own engraved element symbol: no colour chart needed.
Look at the skeleton first: 4-Nitroaniline contains one aromatic 6-membered ring, and students can trace 16 bonds (9 single, 1 double and 6 aromatic). Hand the model round and let students tally the engraved atoms: 6 C + 6 H + 2 N + 2 O, 16 in total. A good fit for lessons on aromaticity and delocalised electrons, as well as on amines and basicity. Its closest structural relatives in the MolGod.org collection are Nitrobenzene (CAS 98-95-3) and 1,1'-Oxybis(4-nitrobenzene) (CAS 101-63-3); printing them side by side makes a quick compare-and-contrast exercise. Functional groups to find on the model: nitro group (-NO2) and primary amino group (-NH2).
MolGod.org builds and releases these models at no cost for chemistry teaching. Teachers: hand out printed copies and ask students to rebuild the structural formula from the model.

A ball-and-stick model of 4-Nitroaniline 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: 221,264 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
Names in other languages: 4-Nitroanilin (de); 4-nitroanilina (it); 4-硝基苯胺 (zh).
