Acetonitrile (C2H3N, CAS 75-05-8) — a free educational 3D molecular model for teachers and students, by MolGod.org. No legend required: the element symbol is engraved on each atom.
Ask the class whether Acetonitrile contains a ring. It does not: 6 atoms and 5 bonds (4 single and 1 triple) make up an open structure. How many atoms can the class find? The engraved spheres give 2 C + 3 H + 1 N, so the answer should be 6. On the printed model, students can point to the nitrile (cyano) group (-C#N).
Teachers: use the model for an exit-ticket question on the structure the class has just studied.
