States of matter — practice question

Organohalogen compounds can be hydrolysed. $\text{R-Cl} + \text{H}_2\text{O} \rightarrow \text{R-OH} + \text{HCl}$.
(a)[3]

State the hydrolysis-rate order of the following compounds: $\text{CH}_3\text{CH}_2\text{CH}_2\text{Cl}$, $\text{CH}_3\text{CH}_2\text{COCl}$ and $\text{C}_6\text{H}_5\text{Cl}$. Explain your answer.

(b)[2]

Name the three functional groups in aminolaevulinic acid.

(c(i))

Aminolaevulinic acid reacts readily with bromoethane. On the diagram, show the mechanism for the first step of this reaction. Include all required curly arrows, lone pairs and relevant dipoles.

(c(ii))

Name the mechanism in (c)(i).

(c(iii))[5]

Identify the non-organic product formed in this reaction.

(d)[3]

Three reactions of aminolaevulinic acid are shown. Draw the structures of the products W, X and Y in the boxes below.

(e)[2]

Aminolaevulinic acid can undergo polymerisation. Draw the structure of the polymer showing two repeat units. The linkages between the monomer units should be shown fully displayed.
