Question
One of these compounds is synthesized via successive condensation reactions of para-phenyl⋅enediamine and terephthaloyl (“ter-ruh-phuh-THAH-loyal”) chloride. For 10 points each:
[10m] Name these compounds, which include aramids such as Kevlar. These compounds contain many moieties consisting of an amine group bonded to a carbonyl group.
ANSWER: polyamides [accept aromatic polyamides; prompt on amides]
[10e] The “6” kind of this polyamide is formed from the ring-opening polymerization of caprolactam (“kah-pro-LAK-tam”). Many outdoor garments and activewear are made of this stretchy synthetic fiber.
ANSWER: nylon [accept Nylon 6; accept Nylon 66]
[10h] In 2003, Dervan et al. developed a polyamide composed of pyrrole and this molecule that can tightly bind the minor groove of DNA. In one technique, a solution containing this molecule is added to a nickel-NTA column to promote the elution of molecules of interest.
ANSWER: imidazole [accept pyrrole-imidazole polyamide]
