1-Chloro-4-iodobutane 3D Model — CAS 10297-05-9

Model Overview & Print Notes

Summary 1-Chloro-4-iodobutane (C4H8ClI, CAS 10297-05-9) — a free educational 3D molecular model for teachers and students, by MolGod.org. Each atom is labelled with its own engraved element symbol: no colour chart needed. Teachers who print molecules quickly meet the same gap: the file defines spheres and sticks, but not which element each sphere stands for. We build the label into the model: each sphere bears its recessed element symbol, readable by eye and by fingertip. The purpose is educational: teachers get printable files built to shorten the step of 'which atom is this?' and leave more time for chemistry. Instead of building a model from scratch, a teacher can go straight from the molecule's name to a file in the slicer. More about the hypothesis we are testing with these models: https://molgod.org/engraved-molecular-models/ . 1-Chloro-4-iodobutane has no rings at all: its 14 atoms form an open chain held together by 13 bonds (all of them single). Students work from the model back to the formula C4H8ClI: the symbol count is 4 C + 8 H + 1 Cl + 1 I, or 14 atoms all told. Functional groups to find on the model: C-Cl bond and C-I bond. Worth bringing out when the syllabus reaches organohalogen compounds and carbon-halogen bonds. For compare-and-contrast work, 1,2-Dichloroethane (CAS 107-06-2) is structurally close to it in this collection. MolGod.org offers this engraved model free to anyone teaching or learning chemistry. Teachers: pass the model round at the start of the lesson, before showing any diagram. Download it, print it and use it in your teaching. When you publish a photo, a worksheet or a remix, CC BY-SA 4.0 requires you to credit "MolGod.org" as the author of the model, link to the original and to the licence, indicate any changes and share remixes under the same licence (the ready attribution line is below). No sign-up, no fees and no review required. Printed it? Used it in class? Please share a quick review in the comments and suggest how we can make our molecules even more useful for learning.

Feel free to discuss the model here, compare notes with other educators, or contact us; every conversation helps us build better teaching models. Every request counts: tell us which molecule you need and we will make its 3D model specially for your students.
