Ethanolamine, C₂H₇NO, 141-43-5

Ethanolamine (C2H7NO, CAS 141-43-5) — a free educational 3D molecular model for teachers and students, by MolGod.org. Every sphere shows which element it is through an engraved symbol, not a colour code. A one-colour print of a molecule hides the most basic information, which element each atom is, because STL keeps no colour data. The MolGod approach puts the information where students look for it, on the atom: every sphere is engraved with its symbol. MolGod's aim is to make the first step of reading a molecule, recognising its atoms, faster for students, so that bonding and geometry become the focus. Teachers skip the modelling and labelling work entirely: download the file, set the scale in the slicer and print. The research behind the idea, and how we plan to test it, is described at The story behind these engraved molecule models. Follow the chain of Ethanolamine from end to end: 11 atoms, 10 bonds (all of them single) and no ring anywhere. Counting task: 2 C + 7 H + 1 N + 1 O gives 11 engraved spheres; can the class rebuild the formula C2H7NO from the model alone? Functional groups to find on the model: hydroxyl group (-OH) and primary amino group (-NH2). Topics it supports in class: alcohols and hydrogen bonding, as well as amines and basicity. Students who finish early can look up N-(2-Hydroxyethyl)ethylenediamine (CAS 111-41-1) and Ethylene Glycol (CAS 107-21-1), the closest neighbours in the collection, and list what differs. MolGod.org shares these models for free to make chemistry tangible in the classroom. Teachers: pass the model round at the start of the lesson, before showing any diagram. The model is yours to download, print and teach with. CC BY-SA 4.0 sets four simple conditions for anything you publish with it: credit "MolGod.org" as the model's author, link the original and the licence, say what you changed, and share derivatives alike. Copy the attribution line below to get it right. There is no registration, no payment and no obligation to rate it. Teachers and students, we read every comment. Tell us in a review how the model worked for you and what we could do better for education; for longer feedback write to Ask us for another molecule. We enjoy hearing from classrooms: start a conversation in the comments or get in touch with us directly, we are glad to help. All we need is a CAS number: from it MolGod generates the 3D structure, engraves every atom and prepares the STL.

STL mesh: 118,674 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
