4-Chlorobenzotrichloride 3D Molecular Model — CAS 5216-25-1

4-Chlorobenzotrichloride (C7H4Cl4, CAS 5216-25-1) — a free educational 3D molecular model for teachers and students, by MolGod.org. Each atom is labelled with its own engraved element symbol: no colour chart needed.

At its heart, 4-Chlorobenzotrichloride is built around one aromatic 6-membered ring. The model shows 15 bonds: 9 single and 6 aromatic. A five-minute warm-up: read the symbol on every sphere and write down the totals (7 C + 4 H + 4 Cl = 15 atoms). On the printed model, students can point to the four C-Cl bonds. It makes aromaticity and delocalised electrons, as well as organohalogen compounds and carbon-halogen bonds easier to see. Place it beside Benzotrichloride (CAS 98-07-7) and 4-Chlorostyrene (CAS 24991-47-7) and ask students which features are shared and which are not.

Teachers and students can use this MolGod.org model free of charge. Teachers: hand out printed copies and ask students to rebuild the structural formula from the model.

A ball-and-stick model of 4-Chlorobenzotrichloride with each element symbol recessed into its atom sphere, generated by MolGod.org from a PubChem-computed 3D conformer (not an experimental crystal structure); atomic coordinates and connectivity are unchanged. STL mesh: 226,358 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
