Chloroform 3D Molecular Model — CAS 67-66-3

Chloroform (CHCl3, CAS 67-66-3) — a free educational 3D molecular model for teachers and students, by MolGod.org. Whatever the filament colour, each atom reads clearly thanks to its engraved symbol.

Lay Chloroform on the desk and search for a ring: there isn't one. Its 5 atoms hang together through 4 bonds (all of them single). Hand the model round and let students tally the engraved atoms: 1 C + 1 H + 3 Cl, 5 in total. Name-and-locate exercise: students touch the three C-Cl bonds and afterwards write the name of every group they touched. Students meeting organohalogen compounds and carbon-halogen bonds for the first time can hold an example in their hands. No hydrogen-bond donors and no acceptors (computed): set it beside an alcohol to talk about intermolecular forces.

MolGod.org publishes its molecular models free of charge for teachers and students. Teachers: the engraved symbols let students work with the model without a separate key.

A ball-and-stick model of Chloroform with each element symbol recessed into its atom sphere, generated by MolGod.org from a PubChem-computed 3D conformer (not an experimental crystal structure); atomic coordinates and connectivity are unchanged. STL mesh: 77,668 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.

Names in other languages: chloroforme (fr); cloroformio (it); 氯仿 (zh).
