1. Shown below is the overall reaction for the synthesis of Nylon 6-6, a polyamide polymer....
: Synthesis of Nylon (Polyamide) ~ Pre-Lab Assignment Section #- Score - Nylon 6-6 is a condensation polymer. The last two lab handouts pointed out that "condensation reactions are extremely common among a variety of organic functional groups Pick two appropriate functional groups (your choice) and draw structures to show the condensation reaction between them. Identify the functional growps that are reacting, as well as the linkage formed by the condensation. 2. Rather than use a carboxylic acid for the...
what is the theoretical yield for this experiment? ORGANIC POLYMERS: THE SYNTHESIS OF NYLON Nylon's outstanding characteristic in the textile industry is its versatility. It can be made strong enough to stand up under the punishment tire cords must endure, fine enough for sheer, high fashion hosiery, and light enough for parachute cloth and backpacker's tents. Nylon is used both alone and in blends with other fibers, where its chief contributions are strength and abrasion resistance. Nylon washes easily, dries...
III. Shown below, the hydration of 2,5-dimethylhexyn-2,5-diol combines several transformations that we learned into one reaction; hydration of an alkyne and an acid-catalyzed ether synthesis. Hg2+, H2SO4 (dil) HO OH H20, A Provide a complete electron-pushing mechanism for this reaction shown below in parts A and B.
