Acetic Anhydride 3D Model — CAS 108-24-7

Acetic Anhydride (C4H6O3, CAS 108-24-7) — a free educational 3D molecular model for teachers and students, by MolGod.org. Every atom carries its engraved element symbol (C, H, O, N...), so no colour key is needed. Acetic Anhydride is a chain molecule with no ring: 12 bonds (10 single and 2 double) connect its 13 atoms. Give each pair of students the model and a blank sheet: recording every engraved symbol should lead them to 4 C + 6 H + 3 O, which is 13 atoms. For a lesson on isomerism, print i…
