3-Bromo-5-chloro-2-methoxypyridine

3-Bromo-5-chloro-2-methoxypyridine (C6H5BrClNO, CAS 102830-75-1) — a free educational 3D molecular model for teachers and students, by MolGod.org. Read the atoms directly: each sphere bears an engraved element symbol. Start with the ring system: 3-Bromo-5-chloro-2-methoxypyridine has one aromatic 6-membered ring; in total the model carries 15 bonds (9 single and 6 aromatic, drawn in Kekulé form). Counting task: 6 C + 5 H + 1 Br + 1 Cl + 1 N + 1 O gives 15 engraved spheres; can the class rebuild the formula C6H5BrClNO from the model alone? Ask the class to locate the ether linkage (C-O-C), the pyridine-type ring nitrogen, the C-Cl bond and the C-Br bond and name each one.
