Nitrobenzene 3D Molecular Model — CAS 98-95-3

Nitrobenzene (C6H5NO2, CAS 98-95-3) — a free educational 3D molecular model for teachers and students, by MolGod.org. Element symbols are cut into each atom sphere: a self-labelled teaching aid. A one-colour print of a molecule hides the most basic information, which element each atom is, because STL keeps no colour data. We build the label into the model: each sphere bears its recessed element symbol, readable by eye and by fingertip. We design these models so that students can name every atom straight away and concentrate on connectivity, bond types and shape. Teachers skip the modelling and labelling work entirely: download the file, set the scale in the slicer and print. Curious about the science behind the engraving? The project page is at How the engraved atom letters are designed. Start with the ring system: Nitrobenzene has one aromatic 6-membered ring; in total the model carries 14 bonds (7 single, 1 double and 6 aromatic, drawn in Kekulé form). Students work from the model back to the formula C6H5NO2: the symbol count is 6 C + 5 H + 1 N + 2 O, or 14 atoms all told. Name-and-locate exercise: students find the nitro group (-NO2) on the model and afterwards write the name of every group they found. Topics it supports in class: aromaticity and delocalised electrons. Want a comparison? The most similar structures in the MolGod.org collection are 4-Nitroaniline (CAS 100-01-6) and 4-Nitropyridine N-oxide (CAS 1124-33-0). MolGod.org shares these models for free to make chemistry tangible in the classroom. Teachers: use the model for an exit-ticket question on the structure the class has just studied. Print it, hand it round and build a lesson around it. 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. Your comments decide what we improve next, from engraving depth to which molecules we add.
