Question

Kevlar®, a polymeric aromatic amide, is synthesized from the monomers p-phenylenediamine (left) and terephthaloyl chlo-ride (right). The polymer strands are initially aligned randomly,but they are dissolved and spun to give a lightweight, flexible product that is five times stronger than steel of the same weight.(a) Describe this step in terms of a Lewis acid-base reaction. (b) Would you expect water or ammonia to react faster with an acid chloride? Explain.
