Pentamidine 3D Molecular Model — CAS 100-33-4

Pentamidine (C19H24N4O2, CAS 100-33-4) — a free educational 3D molecular model for teachers and students, by MolGod.org. Each atom is labelled with its own engraved element symbol: no colour chart needed. Look at the skeleton first: Pentamidine contains two 6-membered rings, both aromatic, and students can trace 50 bonds (36 single, 2 double and 12 aromatic, drawn in Kekulé form). Give each pair of students the model and a blank sheet: recording every engraved symbol should lead them to 19 C +…
