P-Toluenesulfonic acid 3D Model — CAS 104-15-4

P-Toluenesulfonic acid (C7H8O3S, CAS 104-15-4) — a free educational 3D molecular model for teachers and students, by MolGod.org. Read the atoms directly: each sphere bears an engraved element symbol. In P-Toluenesulfonic acid the ring system sets the overall shape: one aromatic 6-membered ring. Altogether 19 bonds hold the model together (11 single, 2 double and 6 aromatic, drawn in Kekulé form). Quick starter: ask students to count the engraved symbols (7 C + 8 H + 3 O + 1 S) and check that they add up to 19 atoms and the formula C7H8O3S. It makes aromaticity and delocalised electrons easier to see.
