7. When asymmetric alkenes polymerize (such as chloroethene to produce PVC), the pendant group like chlorine can be arranged in different ways. An arrangement in which the -Cl groups are arranged on the same side of the polymer chain is called a(n) , a. Atactic b. Isotactic arrangement. c. Syndiotactic d. Sporadic 8. Kevlar is a type of polymer which has a great resistance to tear. Its application includes its use in making bulletproof vests and radial tires. The two monomers used to make Kevlar are the following: H H H-O- c-0-H H-N- -N-H Monomer One Monomer Two When these two monomers join a. A molecule of CO2 will be eliminated and an ester linkage will form b. Nothing will be eliminated and the two monomers will be linked through a hydrogen to hydrogen bond c. A water molecule will be eliminated and a peptide linkage will be formed d. Nothing will be eliminated. The two monomers will be linked by a carbon-carbon bond.

1. Formaldehyde (methanal: H2C=0) can be polymerized to produce Delrin (polyoxymethylene), a strong and easily molded plastic. Write a chemical reaction that shows the formation of this polymer.

Polymers that can conduct electricity are called conducting polymers. Some polymers can be made semiconducting; others can benearly metallic. Polyacetylene is an example of a polymer that is a semiconductor. It can also be doped to increase its conductivity.Polyacetylene is made from acetylene in a reaction that looks simple but is actually tricky to do:H—C≡ C— HAcetylene [— CH=CH— ]n Polyacetylene(a) What is the hybridization of the carbon atoms, and the geometry around those atoms, in acetylene and in polyacetylene?(b) Write a balanced equation to make polyacetylene from acetylene.
