Under suitable conditions, propene polymerises to form poly(propene). Poly(propene) exhibits stereoisomerism. Identify the type of polymerisation that forms poly(propene) from 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 associated with 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.
The molecular ion peak in the spectrum in Fig. 4.2 has relative abundance 34.7. Calculate the relative abundance of the $[\mathrm{M}+1]^+$ peak in this spectrum.
