Phenethyl Cinnamate 3D Molecular Model — CAS 103-53-7

Phenethyl Cinnamate (C17H16O2, CAS 103-53-7) — a free educational 3D molecular model for teachers and students, by MolGod.org. Instead of colour coding, every sphere carries its engraved element symbol.

Teachers who print molecules quickly meet the same gap: the file defines spheres and sticks, but not which element each sphere stands for. The MolGod approach puts the information where students look for it, on the atom: every sphere is engraved with its symbol. We design these models so that students can name every atom straight away and concentrate on connectivity, bond types and shape. The labelling that would otherwise be done with stickers or paint after printing is already part of the file. Teachers and researchers can find the project rationale and validation plan at https://molgod.org/engraved-molecular-models/.

Which rings can the class see in Phenethyl Cinnamate? The answer is two 6-membered rings, both aromatic, joined up by 36 bonds altogether (22 single, 2 double and 12 aromatic, drawn in Kekulé form). Hand the model round and let students tally the engraved atoms: 17 C + 16 H + 2 O, 35 in total. Before any theory, let students hunt on the model for the ester group (-COO-) and the carbon-carbon double bond (C=C). Plan it into a unit on aromaticity and delocalised electrons, as well as on the carbonyl group (C=O). Want a comparison? The most similar structures in the MolGod.org collection are 2-Phenylethyl methacrylate (CAS 28825-60-7) and Phenylethyl isovalerate (CAS 140-26-1).

Part of the MolGod.org free library of engraved molecules for chemistry classrooms. Teachers: use the model for an exit-ticket question on the structure the class has just studied.

Free to print and free to bring into any classroom. If you share a photo, a lesson or an adapted version, the licence (CC BY-SA 4.0) asks for credit to "MolGod.org" as the model's author, a link to the original and to the licence text, a note of what you changed, and the same licence for adaptations; the attribution line below is ready to copy. You don't need an account, you don't pay anything, and a review is entirely up to you. Help us make better models for students! A comment with your honest review, what worked, what was hard to read, what you would change, is the best gift you can give us. More at https://molgod.org/contact/. Curious about bond angles, isomers or where this compound appears in everyday life? Ask below and let's discuss it together. Need another molecule?

A ball-and-stick model of Phenethyl Cinnamate 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: 457,794 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
