1,1'-(1,2-Ethanediylbis(oxy))bis(ethene)

1,1'-(1,2-Ethanediylbis(oxy))bis(ethene) (C6H10O2, CAS 764-78-3) — 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. Follow the chain of 1,1'-(1,2-Ethanediylbis(oxy))bis(ethene) from end to end: 18 atoms, 17 bonds (15 single and 2 double) and no ring anywhere. Students work from the model back to the formula C6H10O2: the symbol count is 6 C + 10 H + 2 O, or 18 atoms all told. This molecule gives students these functional groups to identify: two ether linkages (C-O-C) and two carbon-carbon double bonds (C=C).
