Description

This entry presents Benzyl alcohol (C7H8O; CAS 100-51-6; PubChem CID 244 (https://pubchem.ncbi.nlm.nih.gov/compound/244)) as a 3D-printable ball-and-stick model in which every atom carries its engraved element symbol (C, H, O), so the model can be read without a colour key. Atomic coordinates come from the PubChem-computed 3D conformer (not an experimental crystal structure); coordinates and connectivity are unchanged. Structure at a glance 16 atoms: 7 C, 8 H, 1 O 16 bonds: 10 single, 6 aromatic One aromatic 6-membered ring Functional group: one hydroxyl group (-OH) One hydrogen-bond donor and one acceptor (computed) Fraction of sp3-hybridised (tetrahedral) carbon atoms: 0.14 (computed) Use in teaching Counting task: students tally the engraved symbols (7 C, 8 H, 1 O; 16 atoms) and rebuild the formula C7H8O from the model alone. Aromaticity: identify the aromatic ring and the 6 bonds recorded as aromatic; the model draws them as one Kekulé structure (alternating single and double bonds), while in the real molecule they are delocalised, intermediate between single and double. Functional groups: find the hydroxyl group (-OH) on the model and name it. File and printing STL mesh of 203,912 triangles, a closed (watertight) single solid. Coordinates are in ångström and STL stores no unit, so scale the model deliberately in your slicer. Measured bounding box: 5.509 × 5.58 × 4.603 Å; at scale factor 10 (1 Å to 10 mm, file read in millimetres) the print measures about 55.1 × 55.8 × 46.0 mm.
