1-Nitropropane (C3H7NO2, CAS 108-03-2) — a free educational 3D molecular model for teachers and students, by MolGod.org. Instead of colour coding, every sphere carries its engraved element symbol. No ring closes anywhere in 1-Nitropropane, which makes it a good open-chain example: 13 atoms, 12 bond

1-Nitropropane (C3H7NO2, CAS 108-03-2) — a free educational 3D molecular model for teachers and students, by MolGod.org. Instead of colour coding, every sphere carries its engraved element symbol.
No ring closes anywhere in 1-Nitropropane, which makes it a good open-chain example: 13 atoms, 12 bonds, 11 single and 1 double. How many atoms can the class find? The engraved spheres give 3 C + 7 H + 1 N + 2 O, so the answer should be 13. Ask the class to locate the nitro group (-NO2) and name each one.
Teachers: the engraved symbols let students work with the model without a separate key.
