Diethyl Phthalate (C12H14O4, CAS 84-66-2) — a free educational 3D molecular model for teachers and students, by MolGod.org. No legend required: the element symbol is engraved on each atom.
Ask students to describe the framework of Diethyl Phthalate before anything else: one aromatic 6-membered ring. Then count the bonds together; there are 30 (22 single, 2 double and 6 aromatic, drawn in Kekulé form). Counting task: 12 C + 14 H + 4 O gives 30 engraved spheres; can the class rebuild the formula C12H14O4 from the model alone? Use it when you teach aromaticity and delocalised electrons, as well as the carbonyl group (C=O).
