The table below shows some information about two alkenes, propene and butene.
| Name of alkene | Molecular formula | Structure |
|---|---|---|
| Propene | (i) | HHH∣∣∣C=C−C−H∣∣HH\begin{array}{ccccc} \text{H} & & \text{H} & & \text{H} \\ \vert{} & & \vert{} & & \vert{} \\ \text{C} & = & \text{C} & - & \text{C} - \text{H} \\ \vert{} & & & & \vert{} \\ \text{H} & & & & \text{H} \end{array}H∣C∣H=H∣C−H∣C−H∣H |
| Butene | C4H8\text{C}_4\text{H}_8C4H8 | (ii) |
Complete the table by providing:
