Methyl 2-Bromo-4-nitrobenzoate (C8H6BrNO4, CAS 100959-22-6) — a free educational 3D molecular model for teachers and students, by MolGod.org. Read the atoms directly: each sphere bears an engraved element symbol.
At its heart, Methyl 2-Bromo-4-nitrobenzoate is built around one aromatic 6-membered ring. The model shows 20 bonds: 12 single, 2 double and 6 aromatic, drawn in Kekulé form. How many atoms can the class find? The engraved spheres give 8 C + 6 H + 1 Br + 1 N + 4 O, so the answer should be 20. Team task: with the model in hand, each group marks the ester group (-COO-), the nitro group (-NO2) and the C-Br bond, then writes down what they found.
