Draw the repeating structural units of the step-growth polymers you would expect to obtain from the following reactions. (a) \[BrC{{H}_{2}}C{{H}_{2}}C{{H}_{2}}Br\]\[+HOC{{H}_{2}}C{{H}_{2}}C{{H}_{2}}OH\xrightarrow{Base}\] (b) \[HOC{{H}_{2}}C{{H}_{2}}OH+HOOC{{(C{{H}_{2}})}_{6}}COOH\xrightarrow{{{H}^{+}}}\]

Answer:

                (a) \[-C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}O-\] (b) \[-OC{{H}_{2}}C{{H}_{2}}O-CO{{(C{{H}_{2}})}_{6}}CO-\]
