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. Symbols are engraved into every atom, so students read atoms by symbol, not by colour. Turn the model in your hand to see the shape of 4-Nitroaniline: one aromatic 6-membered ring, and 16 bonds in total (9 single, 1 double and 6 aromatic). Quick starter: ask students to count the engraved symbols (6 C + 6 H + 2 N + 2 O) and check that they add up to 16 atoms and the formula C6H6N2O2. On the printed model, students can point to the nitro group (-NO2) and the primary amino group (-NH2). Topics it supports in class: aromaticity and delocalised electrons, as well as amines and basicity. Pair it with Nitrobenzene (CAS 98-95-3) and 1,1'-Oxybis(4-nitrobenzene) (CAS 101-63-3) from the same collection to compare closely related structures. This model is part of the free MolGod.org collection of engraved molecules for education. Teachers: pair it with the MolGod.org record to connect the 3D shape with identifiers and data.
