4-Nitroaniline molecular model (C6H6N2O2, CAS 100-01-6): a free, print-ready ball-and-stick model with the element symbol engraved on every atom, designed for chemistry lessons.
Which rings can the class see in 4-Nitroaniline? The answer is one aromatic 6-membered ring, joined up by 16 bonds altogether (9 single, 1 double and 6 aromatic). Students work from the model back to the formula C6H6N2O2: the symbol count is 6 C + 6 H + 2 N + 2 O, or 16 atoms all told. Functional groups to find on the model: nitro group (-NO2) and primary amino group (-NH2). Topics it supports in class: aromaticity and delocalised electrons, as well as amines and basicity. Place it beside Nitrobenzene (CAS 98-95-3) and 1,1'-Oxybis(4-nitrobenzene) (CAS 101-63-3) and ask students which features are shared and which are not.
Printing: the STL is in angstrom units - scale it 10x in the slicer (1 angstrom = 10 mm). Use supports under the bonds; PLA works well.
