(a)[1]
State the $\text{H-C-H}$ bond angle at the terminal $=\text{CH}_2$ group in propene?
(b(i))[1]
When propene reacts, 1,2-dichloropropane, $\text{CH}_3\text{CHClCH}_2\text{Cl}$, is produced. State fully what type of reaction this is.
(b(ii))[3]
When cyclopropane reacts with chlorine, three different compounds with molecular formula $\text{C}_3\text{H}_4\text{Cl}_2$ may be produced. Draw displayed structures for each of these three compounds.
