Ethyl (triphenylphosphoranylidene)acetate (C22H21O2P, CAS 1099-45-2) — 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.
Start with the ring system: Ethyl (triphenylphosphoranylidene)acetate has three 6-membered rings, all of them aromatic; in total the model carries 48 bonds (28 single, 2 double and 18 aromatic, drawn in Kekulé form). A five-minute warm-up: read the symbol on every sphere and write down the totals (22 C + 21 H + 2 O + 1 P = 46 atoms). Before any theory, let students hunt on the model for the ester group (-COO-).
