Alkenes can be produced by cracking large hydrocarbon molecules to form smaller hydrocarbon molecules.
Which equations represent possible reactions when tetradecane, ${C_{14}}{H_{30}}$, is cracked?
1 ${C_{14}}{H_{30}} \to {C_2}{H_6} + {C_3}{H_6} + {C_4}{H_8} + {C_5}{H_{10}}$
2 ${C_{14}}{H_{30}} \to {H_2} + {C_2}{H_4} + {C_3}{H_6} + {C_4}{H_8} + {C_5}{H_{10}}$
3 ${C_{14}}{H_{30}} \to {C_2}{H_6} + 4{C_3}{H_6}$
4 ${C_{14}}{H_{30}} \to {C_2}{H_6} + {C_3}{H_8} + {C_9}{H_{18}}$
