3,4-Dihydroxybenzaldehyde (C7H6O3, CAS 139-85-5) — 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. Ask students to describe the framework of 3,4-Dihydroxybenzaldehyde 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). Counting task: 7 C + 6 H + 3 O gives 16 engraved spheres; can the class rebuild the formula C7H6O3 from the model alone? Functional groups to find on the model: aldehyde group (-CHO) and two phenolic hydroxyl groups (Ar-OH).
