Draw the displayed formula for compound P.
Identify the reagent(s) and conditions for reactions 1 and 2.
Draw the structure of the repeat unit of polymer Q.
Complete the reaction scheme to show the mechanism for the reaction between 1-bromobutane and $\text{OH}^-(aq)$ that forms R. Include every necessary charge, dipole, lone pair and curly arrow, together with the structure of R.
Identify the type of reaction that occurs when but-1-ene reacts with steam.
State what can be deduced about the structure of S from its reaction with alkaline aqueous iodine.
Explain why S is the major product of the reaction of but-1-ene with steam.
Draw the skeletal formulae of S, T and U.
Write an equation to represent the oxidation of S to U by acidified potassium dichromate(VI). You should use $[O]$ to represent the oxidising agent.
$\mathrm{CH}_3$(CH$_2$)$_3$CO$_2$H is a colourless liquid with an unpleasant odour. It reacts with methanol in the presence of an acid catalyst to give an organic product V, which has a pleasant fruity smell.
Name V.
A student analysed CH$_3$(CH$_2$)$_3$CO$_2$H, methanol and V using infra-red spectroscopy. The spectra were returned to the student without labels. Identify which of the infra-red spectra, X, Y or Z, matches V. Explain your answer with reference to relevant features of the three spectra in the region above $1500\ \text{cm}^{-1}$.
