1-Ethenyl-3-methylbenzene — CAS 100-80-1

1-Ethenyl-3-methylbenzene (C9H10, CAS 100-80-1) — 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. Look at the skeleton first: 1-Ethenyl-3-methylbenzene contains one aromatic 6-membered ring, and students can trace 19 bonds (12 single, 1 double and 6 aromatic, drawn in Kekulé form). How many atoms can the class find? The engraved spheres give 9 C + 10 H, so the answer should be 19. On the printed model, students can point to the carbon-carbon double bond (C=C).
