5070Alkenes

Alkenes can be produced by the cracking of alkanes, such as decane, C10H22. Which equation shows the cracking of decane to produce two different alkenes and at least one other product?

  1. AC10H22 → 2C2H4 + C3H6 + C4H10
  2. BC10H22 → H2 + 2C2H4 + C3H6 + C5H10
  3. CC10H22 → 2C3H6 + C4H10
  4. DC10H22 → H2 + 2C2H4 + 2C3H6
