Trimethyl(4-vinylphenyl)silane 3D Molecular Model — CAS 1009-43-4

Trimethyl(4-vinylphenyl)silane (C11H16Si, CAS 1009-43-4) — a free educational 3D molecular model for teachers and students, by MolGod.org. Read the atoms directly: each sphere bears an engraved element symbol. Start with the ring system: Trimethyl(4-vinylphenyl)silane has one aromatic 6-membered ring; in total the model carries 28 bonds (21 single, 1 double and 6 aromatic, drawn in Kekulé form). Hand the model round and let students tally the engraved atoms: 11 C + 16 H + 1 Si, 28 in total. Ask the class to locate the carbon-carbon double bond (C=C) and name each one. It makes aromaticity and delocalised electrons easier to see. Pair it with 4-Chlorostyrene (CAS 24991-47-7) and styrene (CAS 100-42-5) from the same collection to compare closely related structures. Part of the MolGod.org free library of engraved molecules for chemistry classrooms. Teachers: let students set the model beside a skeletal formula and list what the drawing omits.
