Identify the kind of reaction that takes place in reaction 1.
Suggest a suitable reagent for reaction 2.
Reaction 3 is an elimination reaction. Write an equation for this reaction and state the solvent and conditions used.
$\mathrm{C_2H_5CH_2OH}$ can be converted directly into $\mathrm{C_3H_6}$. Suggest the reagent and conditions for this conversion.
Under suitable conditions, propene polymerises to form poly(propene). Poly(propene) exhibits stereoisomerism. Identify the type of polymerisation that converts propene into poly(propene).
Define stereoisomerism.
Draw a section of poly(propene), showing two repeat units. Use your diagram to identify the type of stereoisomerism shown by poly(propene). Explain your answer.
State two difficulties linked to the disposal of poly(propene).
Under different conditions, two molecules of propene can combine to form compounds X and Y. Name X.
Fig. 4.2 shows the mass spectrum of either compound X or compound Y. Identify which of X and Y gives this mass spectrum. Give one reason for your answer, referring to the fragmentation pattern.
In the spectrum in Fig. 4.2, the molecular ion peak has relative abundance 34.7. Calculate the relative abundance of the $[\mathrm{M}+1]^+$ peak in this spectrum.
