Chapter 21: Q139AE (page 889)

Consider the following polymer:

Is this polymer a homopolymer or a copolymer, and is it formed by addition polymerization or condensation polymerization? What is (are) the monomer(s) for this polymer?

Short Answer

Expert verified

It is copolymer made of ethylene glycol and terephthalic acid. It is formed with a condensation reaction. Ethylene glycol and terephthalic acid are the monomers for this polymer.

Step by step solution

01

To find the monomers

This polymer is copolymer because it is made of two monomers terephthalic acid and ethylene glycol. Condensation reactions occur because water molecule is the product of the polymerization process.

02

Structure of the monomers

Hence it is copolymer made of ethylene glycol and terephthalic acid. It is formed with a condensation reaction.

Polychlorinated dibenzo-p-dioxins, or PCDDs, are highly toxic substances that are present in trace amounts as by-products of some chemical manufacturing processes. They have been implicated in a number of environmental incidents-for example, the chemical contamination at Love Canal and the herbicide spraying in Vietnam. The structure of dibenzo-p-dioxin, along with the customary numbering convention, is

The most toxic PCDD is 2, 3, 7, 8-tetrachloro-dibenzo-pdioxin. Draw the structure of this compound. Also draw the structures of two other isomers containing four chlorine atoms.

Draw cyclic structure for D-ribose and D-mannose.

Isoprene is the repeating unit in natural rubber. The structure of isoprene is

  1. Give a systematic name for isoprene.
  2. When isoprene is polymerized, two polymers of the form

are possible. In natural rubber, the cis configuration is found. The polymer with the trans configuration around the double bond is called gutta percha and was once used in the manufacture of golf balls. Draw the structure of natural rubber and gutta percha showing three repeating units and the configuration around the carbon–carbon double bonds.

Another way of producing highly crosslinked polyesters (see Exercise 84) is to use glycerol. Alkyd resins are a polymer of this type. The polymer forms very tough coatings when baked onto a surface and is used in paints for automobiles and large appliances. Draw the structure of the polymer formed from the condensation of
