Question 23.4: Consider the following polyamide:

Chemistry: Principles and Reactions

Consider the following polyamide:

\begin{matrix} -C-&(CH_2)_4-&C-&N-&(CH_2)_6-&N-&C-&(CH_2)_4-&C-&N-&(CH_2)_6-&N-\\\parallel &&\parallel &\mid &&\mid &\parallel &&\parallel&\mid &&\mid\\O&&O&H&&H &O&&O&H&&H \end{matrix}

Give the structures of the two monomers, dicarboxylic acid and diamine, used to make this
polymer.

STRATEGY

1. Break the polymer into two fragments. Each fragment should be one of the monomers.
2. Add an OH group to the -C=O terminal carbon atoms of the first monomer.
3. Add a H atom to the N terminal atoms of the second monomer.
