Poly(ethylene terephthalate), known as PET or industrially as Dacron, is a polyester synthesized through a condensation reaction between two bifunctional monomers. The monomers, ethylene glycol and terepthalic acid, are given. Add bonds and remove atoms as necessary to show the structure of a two repeat unit portion of a longer polymer chain of PET. You may need to zoom out to see the complete structure of all four monomer units.
