2-Bromo-1-(2,4-dichlorophenyl)ethan-1-one (C8H5BrCl2O, CAS 2631-72-3) — a free educational 3D molecular model for teachers and students, by MolGod.org. Every atom carries its engraved element symbol, so no colour key is needed.
Look at the skeleton first: 2-Bromo-1-(2,4-dichlorophenyl)ethan-1-one contains one aromatic 6-membered ring, and students can trace 17 bonds (10 single, 1 double and 6 aromatic, drawn in Kekulé form). Use the engraved letters like a register: call out each element and tick it off until the class reaches 8 C + 5 H + 1 Br + 2 Cl + 1 O (17 atoms altogether). On the printed model, students can point to the ketone group (C=O), the two C-Cl bonds and the C-Br bond.
