1-Ethoxy-2-(2-methoxyethoxy)ethane 3D Molecular Model — CAS 1002-67-1

1-Ethoxy-2-(2-methoxyethoxy)ethane (C7H16O3, CAS 1002-67-1) — 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.

Lay 1-Ethoxy-2-(2-methoxyethoxy)ethane on the desk and search for a ring: there isn't one. Its 26 atoms hang together through 25 bonds (all of them single). Use the engraved letters like a register: call out each element and tick it off until the class reaches 7 C + 16 H + 3 O (26 atoms altogether). On the printed model, students can point to the three ether linkages (C-O-C). For a lesson on isomerism, print it together with Ethyl orthoformate (CAS 122-51-0) and Dipropylene glycol monomethyl ether (CAS 34590-94-8): the same atoms, arranged differently. Students who finish early can look up Diglyme (CAS 111-96-6) and Diethylene Glycol Monoethyl Ether (CAS 111-90-0), the closest neighbours in the collection, and list what differs.

MolGod.org builds and releases these models at no cost for chemistry teaching. Teachers: print one per group and let students check the structure against the formula.

A ball-and-stick model of 1-Ethoxy-2-(2-methoxyethoxy)ethane 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: 294,958 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
