Draw the organic product $G$ in the box in Fig. 6.1.
In Fig. 6.1, $\text{SOCl}_2$ is shown as the reagent that reacts with $\text{HOOC}\text{COOH}$ to give $G$. Identify another reagent that can also react with $\text{HOOC}\text{COOH}$ to form $G$.
Identify two distinct reagents that oxidise $\text{HOOC}\text{COOH}$ to carbon dioxide and water.
The ionisation of $\text{HOOC}\text{COOH}$ is shown below. $\text{HOOC}\text{COOH} \rightleftharpoons \text{HOOC}\text{COO}^- + \text{H}^+$ $\text{HOOC}\text{COOH}$ is a much stronger acid than methanoic acid, $\text{HCOOH}$. Offer an explanation for this difference in acidity.
Suggest the identity of $J$ by drawing its structure in the box in Fig. 6.2.
Identify the reagents and conditions needed for step 1 and step 2.
Draw one repeat unit of the polymer produced when benzene-1,4-dicarboxylic acid reacts with ethane-1,2-diol, $\text{HOCH}_2\text{CH}_2\text{OH}$. The linkage between the monomers should be shown fully displayed.
State the type of polymerisation that takes place when benzene-1,4-dicarboxylic acid reacts with ethane-1,2-diol and name the linkage formed between the monomers.
