Methanol 3D Molecular Model — CAS 67-56-1

Methanol (CH4O, CAS 67-56-1) — 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.

Ask the class whether Methanol contains a ring. It does not: 6 atoms and 5 bonds (all of them single) make up an open structure. Hand the model round and let students tally the engraved atoms: 1 C + 4 H + 1 O, 6 in total. Before any theory, let students hunt on the model for the hydroxyl group (-OH). Students meeting alcohols and hydrogen bonding for the first time can hold an example in their hands. Hydrogen bonding count (computed): 1 donor, 1 acceptor.

Free for education: MolGod.org publishes engraved molecular models for teachers, students and schools. Teachers: pass the model round at the start of the lesson, before showing any diagram.

A ball-and-stick model of Methanol 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: 67,568 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.

Names in other languages: méthanol (fr); metanolo (it); metanol (pl); 甲醇 (zh).
