Round 6: Tossup 12

Heeger, MacDiarmid, and Shirakawa shared the 2000 Nobel Prize in Chemistry for developing the “conductive” (15[1])type of these molecules. The degree of forming these molecules equals one over one minus the extent of the reaction according to the Carothers (“ker-OTHERS”) equation. Olefin-based examples of these molecules can be formed using a catalyst named for (*) Ziegler and Natta. (10[2])These molecules are usually represented by a chemical formula inside parentheses with a subscript n. These molecules are formed via step-growth and chain-growth mechanisms. For 10 points, kevlar and nylon (10[1])are examples of what type (10[1])of molecules made of monomer subunits? ■END■
