If a high molecular weight linear polyethylene is chlorinated by inducing the substitution of chlorine atoms by hydrogen, if 5% of all hydrogen atoms are replaced, what approximate percentage of chlorine by weight would the product have?

O Macmillan Learning Chemistry: Fundamentals and Principles Davidson presented by Macmillan Learning 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. Select Draw / || | C H 0 3 © Templates More ° ° ° || C CC - OH HO OH HOC - C Erase CC OH HO C C 〃 C H₂ Q2Q
