4-Nitroaniline 3D Molecular Model — CAS 100-01-6

4-Nitroaniline (C6H6N2O2, CAS 100-01-6) — a free educational 3D molecular model for teachers and students, by MolGod.org. Element symbols are cut into each atom sphere: a self-labelled teaching aid.

At its heart, 4-Nitroaniline is built around one aromatic 6-membered ring. The model shows 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. Spot-the-group challenge: can students find the nitro group (-NO2) and the primary amino group (-NH2)? Use it when you teach aromaticity and delocalised electrons, as well as 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.

MolGod.org publishes its molecular models free of charge for teachers and students. Teachers: the engraved symbols let students work with the model without a separate key.

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.
