Pentane 3D Molecular Model — CAS 109-66-0

Pentane (C5H12, CAS 109-66-0) — a free educational 3D molecular model for teachers and students, by MolGod.org. Symbols are engraved into every atom, so students read atoms by symbol, not by colour. There is not a single ring in Pentane; 17 atoms are linked by 16 bonds in an open chain (all of them single). Counting task: 5 C + 12 H gives 17 engraved spheres; can the class rebuild the formula C5H12 from the model alone? A good fit for lessons on saturated carbon chains and tetrahedral (sp3) car…
