About this model

Vanillin (C8H8O3, CAS 121-33-5) — 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 Vanillin before anything else: one aromatic 6-membered ring. Then count the bonds together; there are 19 (12 single, 1 double and 6 aromatic, drawn in Kekulé form). Give each pair of students the model and a blank sheet: recording every engraved symbol should lead them to 8 C + 8 H + 3 O, which is 19 atoms. Where on the model can students see the aldehyde group (-CHO), the phenolic hydroxyl group (Ar-OH) and the ether linkage (C-O-C)? Let them search before you reveal the answer. Worth bringing out when the syllabus reaches aromaticity and delocalised electrons…
