P, Q, R and S display stereoisomerism. Complete Table 4.1 by ticking (✓) the stereoisomerism type shown by each molecule. The stereoisomerism type shown by Q has been provided.
Provide the structural formula for Q.
Name the mechanism in reaction 2.
Complete the equation for reaction 3, with R shown as $\text{C}_4\text{H}_9\text{CN}$. $\text{C}_4\text{H}_9\text{CN} + \ldots$
Use the information in Table 4.2 to show that U contains 7 carbon atoms. Show your working.
Fig. 4.2 shows the infrared spectrum of U. Use Fig. 4.2 and Table 4.3 to identify the functional group in U. Explain your answer fully.
T also contains only one functional group. Use the information in (c)(i) and your answer to (c)(ii) to identify T and U. Draw the structures of T and U in the boxes.
