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?

AC10H22 → 2C2H4 + C3H6 + C4H10
BC10H22 → H2 + 2C2H4 + C3H6 + C5H10
CC10H22 → 2C3H6 + C4H10
DC10H22 → H2 + 2C2H4 + 2C3H6

✓ Correct answer

D: C10H22 → H2 + 2C2H4 + 2C3H6
