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. Instead of colour coding, every sphere carries its engraved element symbol.

Look at the skeleton first: Ethylbenzene contains one aromatic 6-membered ring, and students can trace 18 bonds (12 single and 6 aromatic, drawn in Kekulé form). A five-minute warm-up: read the symbol on every sphere and write down the totals (8 C + 10 H = 18 atoms). Students meeting aromaticity and delocalised electrons for the first time can hold an example in their hands. Isomers in the same collection: o-xylene (CAS 95-47-6). Print them together and ask the class to spot where the atoms moved. For compare-and-contrast work, 4-Ethylphenol (CAS 123-07-9) and benzyl alcohol (CAS 100-51-6) are structurally close to it in this collection.

This model is part of the free MolGod.org collection of engraved molecules for education. Teachers: the engraved symbols let students work with the model without a separate key.

A ball-and-stick model of Ethylbenzene 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: 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).
