Butyric Acid (C4H8O2, CAS 107-92-6) — 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.
Lay Butyric Acid on the desk and search for a ring: there isn't one. Its 14 atoms hang together through 13 bonds (12 single and 1 double). How many atoms can the class find? The engraved spheres give 4 C + 8 H + 2 O, so the answer should be 14. Worth bringing out when the syllabus reaches the carbonyl group (C=O).
Teachers: the engraved symbols let students work with the model without a separate key.
