Isophthalic Acid (C8H6O4, CAS 121-91-5) — 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.
Turn the model in your hand to see the shape of Isophthalic Acid: one aromatic 6-membered ring, and 18 bonds in total (10 single, 2 double and 6 aromatic, drawn in Kekulé form). Quick starter: ask students to count the engraved symbols (8 C + 6 H + 4 O) and check that they add up to 18 atoms and the formula C8H6O4. On the printed model, students can point to the two carboxylic acid groups (-COOH).
