About this model

Sulfuric Acid (H2O4S, CAS 7664-93-9) — a free educational 3D molecular model for teachers and students, by MolGod.org. Whatever the filament colour, each atom reads clearly thanks to its engraved symbol. No ring closes anywhere in Sulfuric Acid, which makes it a good open-chain example: 7 atoms, 6 bonds, 4 single and 2 double. Hand the model round and let students tally the engraved atoms: 2 H + 4 O + 1 S, 7 in total. Spot-the-group challenge: can students find the sulfonic acid group (-SO3H)? Natural follow-up models: Methanesulfonic Acid (CAS 75-75-2) and dimethyl sulfone (CAS 67-71-0), close enough in structure for a spot-the-difference task. When you discuss intermolecular forces, note 2 hydrogen-bond donors and 2 acceptors (computed). MolGod.org publishes its molecular models free of …
