2-Bromo-5-fluorobenzamide (C7H5BrFNO, CAS 1006-34-4) — 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.
Let the group sketch what they see in 2-Bromo-5-fluorobenzamide, namely one aromatic 6-membered ring; afterwards they compare the sketch with the 16 bonds on the model (9 single, 1 double and 6 aromatic, drawn in Kekulé form). Quick starter: ask students to count the engraved symbols (7 C + 5 H + 1 Br + 1 F + 1 N + 1 O) and check that they add up to 16 atoms and the formula C7H5BrFNO. Functional groups to find on the model: amide group (-CO-N<), C-F bond and C-Br bond. Worth bringing out when the syllabus reaches aromaticity and delocalised electrons, the carbonyl group (C=O), as well as organohalogen compounds and carbon-halogen bonds. Place it beside 2-Bromo-5-methylbenzoic acid (CAS 6967-82-4) and Anthranilamide (CAS 88-68-6) and ask students which features are shared and which are not.
Free for education: MolGod.org publishes engraved molecular models for teachers, students and schools. Teachers: use the model for an exit-ticket question on the structure the class has just studied.

A ball-and-stick model of 2-Bromo-5-fluorobenzamide 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: 226,466 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
