This question is about 2-Chloropropane. 2-Chloropropane can also be produced from the reaction of propene with hydrogen chloride. Give the mechanism for this reaction. Include curly arrows and relevant dipoles and lone pairs. (4)

An answer that makes reference to the following points:
- 1 dipole on \(\mathrm{H}-\mathrm{Cl}\)
- 2 curly arrow from \(\mathrm{H}-\mathrm{Cl}\) bond to \(\mathrm{Cl} \delta-\)
- 3 curly arrow from double bond to \(\mathrm{H}(\delta+)\)
- 4 correct carbocation intermediate
- 5 curly arrow from lone pair on Cl
- 6 arrow to \(\mathrm{C}+\) on intermediate
- 7 charge on chloride ion
