2,2-Dibromo-3-nitrilopropionamide 3D Molecular Model — CAS 10222-01-2

2,2-Dibromo-3-nitrilopropionamide (C3H2Br2N2O, CAS 10222-01-2) — a free educational 3D molecular model for teachers and students, by MolGod.org. Element symbols are cut into each atom sphere: a self-labelled teaching aid.

Teachers who print molecules quickly meet the same gap: the file defines spheres and sticks, but not which element each sphere stands for. In a MolGod model the element symbol is part of the sphere's surface, so no separate legend, sticker or colour chart is needed. Every file is meant for the classroom: designed to help learners identify atoms quickly and then explore how they are joined in the molecule. Instead of building a model from scratch, a teacher can go straight from the molecule's name to a file in the slicer. Curious about the science behind the engraving? The project page is at https://molgod.org/engraved-molecular-models/.

2,2-Dibromo-3-nitrilopropionamide has no rings at all: its 10 atoms form an open chain held together by 9 bonds (7 single, 1 double and 1 triple). How many atoms can the class find? The engraved spheres give 3 C + 2 H + 2 Br + 2 N + 1 O, so the answer should be 10. Name-and-locate exercise: students find the amide group (-CO-N<), the nitrile (cyano) group (-C#N) and the two C-Br bonds on the model and afterwards write the name of every group they found. Topics it supports in class: the carbonyl group (C=O), as well as organohalogen compounds and carbon-halogen bonds. Students can look on the model for the 1 donor and 2 acceptors of hydrogen bonds; both figures are computed.

This model is part of the free MolGod.org collection of engraved molecules for education. Teachers: pair it with the MolGod.org record to connect the 3D shape with identifiers and data.

Download it, print it and use it in your teaching. If you share a photo, a lesson or an adapted version, the licence (CC BY-SA 4.0) asks for credit to "MolGod.org" as the model's author, a link to the original and to the licence text, a note of what you changed, and the same licence for adaptations; the attribution line below is ready to copy. Nothing else is needed: no account, no cost, no compulsory feedback. Printed it? Used it in class? Please share a quick review in the comments and suggest how we can make our molecules even more useful for learning. You can also contact us at https://molgod.org/contact/. The comment section is open for discussion: how did you introduce this molecule, and what did your students notice first? Need another molecule? Contact us and we will prepare a 3D model specially for you, starting from its CAS number.

A ball-and-stick model of 2,2-Dibromo-3-nitrilopropionamide 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: 161,002 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
