Alkanes — practice question

Alkenes may be obtained by cracking alkanes, for example decane, $\text{C}_{10}\text{H}_{22}$. Which equation represents the cracking of decane to form two different alkenes and at least one additional product?

  • A$\text{C}_{10}\text{H}_{22} \rightarrow 2\text{C}_2\text{H}_4 + \text{C}_3\text{H}_6 + \text{C}_4\text{H}_{10}$
  • B$\text{C}_{10}\text{H}_{22} \rightarrow \text{H}_2 + 2\text{C}_2\text{H}_4 + \text{C}_3\text{H}_6 + \text{C}_5\text{H}_{10}$
  • C$\text{C}_{10}\text{H}_{22} \rightarrow 2\text{C}_3\text{H}_6 + \text{C}_4\text{H}_{10}$
  • D$\text{C}_{10}\text{H}_{22} \rightarrow \text{H}_2 + 2\text{C}_2\text{H}_4 + 2\text{C}_3\text{H}_6$
