Describe and explain how the acidities of $\text{CHCl}_2\text{CO}_2\text{H}$ and $\text{CH}_2\text{ClCO}_2\text{H}$ relate to one another, and how each compares with ethanoic acid.
For each pair of compounds below, suggest one chemical test, including reagents and conditions, that would distinguish them. State the observations with each compound, and write ‘none’ if that is appropriate.
What type of polymerisation produced this polymer?
Draw the structures of the two monomers $E$ and $F$.
Suggest the conditions needed in the laboratory to make polymer $G$ from $E$ and $F$.
One of the monomers, $E$ or $F$, could be modified to produce a more rigid polymer of a similar chemical type to $G$. Indicate which of the two monomers you would change, and suggest a structure for the new monomer. Monomer to be changed ($E$ or $F$) ………………….. Structural formula of the new monomer …………………..
