Packet 6: Tossup 12

Heeger, MacDiarmid, and Shirakawa shared the 2000 Nobel Prize in Chemistry for developing the “conductive” (15[1])type of these molecules. (15[3])The (-5[1])degree of forming these molecules (15[1])equals (15[1])one over one minus the extent of the reaction (15[1])according to the Carothers (15[1])(“ker-OTHERS”) equation. (15[4])Olefin-based (15[2])examples (15[1])of these molecules can be formed using a catalyst named for (*) Ziegler (10[2])and Natta. (10[3])These (10[1])molecules are usually represented by (10[1])a chemical formula inside (10[1])parentheses (10[1])with a subscript (10[2])n. (10[1])These (10[1])molecules (10[1])are formed via step-growth (10[1])and chain-growth mechanisms. (10[2])For (10[1])10 points, (10[1])kevlar and nylon (10[1])are (10[1])examples of what (10[1])type (10[1])of molecules made of monomer subunits? ■END■
