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. Each atom is labelled with its own engraved element symbol: no colour chart needed. Ask students to describe the framework of 4-Nitroaniline before anything else: one aromatic 6-membered ring. Then count the bonds together; there are 16 (9 single, 1 double and 6 aromatic, drawn in Kekulé form). Students work from the model back to the formula C6H6N2O2: the symbol count is 6…
