Ethylbenzene 3D Molecular Model — CAS 100-41-4

Ethylbenzene (C8H10, CAS 100-41-4) — a free educational 3D molecular model for teachers and students, by MolGod.org. Symbols are engraved into every atom, so students read atoms by symbol, not by colour. Turn the model in your hand to see the shape of Ethylbenzene: one aromatic 6-membered ring, and 18 bonds in total (12 single and 6 aromatic, drawn in Kekulé form). Use the engraved letters like a register: call out each element and tick it off until the class reaches 8 C + 10 H (18 atoms altogether). Plan it into a unit on aromaticity and delocalised electrons. Isomers in the same collection: o-xylene (CAS 95-47-6). Print them together and ask the class to spot where the atoms moved. Students who finish early can look up 4-Ethylphenol (CAS 123-07-9) and benzyl alcohol (CAS 100-51-6), the closest neighbours in the collection, and list what differs. This model is part of the free MolGod.org collection of engraved molecules for education. Teachers: print one per group and let students check the structure against the formula.

STL mesh: 218,500 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer. Names in other languages: Ethylbenzol (de); éthylbenzène (fr); etilbenzene (it); Ethylbenzeen (nl); etylobenzen (pl); 乙苯 (zh).
