State and explain how the hydrolysis rates compare for these compounds: $\text{CH}_3\text{CH}_2\text{Cl}$, $\text{CH}_3\text{COCl}$, $\text{C}_6\text{H}_5\text{Cl}$.
Epitabidine is a weak base. State what the term weak base means.
A molecule of epibatidine has two nitrogen atoms, and either can behave as a base. Epibatidine reacts with $\text{HCl(aq)}$. Complete the structure to suggest the product formed in this reaction.
Polyamides, such as nylon-6, may be made from a monomer containing both an amine and an acyl chloride functional group. When the nylon-6 monomer is hydrolysed, bonds are broken and formed. If you think about the two steps in the reaction mechanism, complete the table by putting one tick (✓) in each row to show the types of bonds broken and formed during the mechanism.
Draw two repeat units of nylon-6. The amide bond must be shown in full.
An addition polymer formed from two different alkene monomers is called a co-polymer. A section of a polyalkene co-polymer is shown. Draw the structures of the two alkene monomers that form this co-polymer.
Explain why polyamides usually biodegrade more readily than polyalkenes.
Deduce what compound $\text{H}$ is and draw its structure in the box.
Suggest reagents and conditions for each of steps $1$-$3$ used to prepare phenylethene from benzene.
