Glycidol 3D Molecular Model — CAS 556-52-5

Glycidol (C3H6O2, CAS 556-52-5) — 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.

Let the group sketch what they see in Glycidol, namely one 3-membered ring; afterwards they compare the sketch with the 11 bonds on the model (all of them single). Counting task: 3 C + 6 H + 2 O gives 11 engraved spheres; can the class rebuild the formula C3H6O2 from the model alone? Where on the model can students see the hydroxyl group (-OH) and the epoxide ring (three-membered C-O-C ring)? Let them search before you reveal the answer. There is one stereocentre in Glycidol; the configuration is not specified in this record, so students can work out what the R and S forms would look like. Teachers covering chirality, enantiomers and CIP (R/S) rules, alcohols and hydrogen bonding, as well as ring strain in three-membered rings will find it a concrete example.

MolGod.org publishes its molecular models free of charge for teachers and students. Teachers: use it as a hands-on starter before drawing the structural formula on the board.

A ball-and-stick model of Glycidol 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: 131,496 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.

Names in other languages: glicidolo (it); 缩水甘油 (zh).
