Molecules of T occur as a pair of stereoisomers. Name the type of stereoisomerism shown by molecules of T. Explain your answer.
Two organic products are made when a sample of T is heated under reflux with excess acidified concentrated KMnO$_4$. Draw the structures of the two organic products from this reaction in the boxes.
Identify a reagent that is suitable for reaction 1.
Identify the reagent together with the conditions needed for reaction 2.
Suggest which product formed in reaction 2 has the higher yield. Explain your answer.
Predict the observations for each test-tube. Explain your answer using the functional groups in Q and R.
When $\text{PCl}_5(s)$ is added to separate samples of Q and R at room temperature, both react vigorously. Complete the equation shown in Fig. 3.4 to show the reaction that takes place when R reacts with $\text{PCl}_5(s)$.
Suggest why the samples of Q and R need to be dried before $\text{PCl}_5$ is added. Include an equation that supports your answer.
