Alkanes — practice question

When ultraviolet radiation is present, butane reacts with chlorine. What equation represents this reaction?

  • A$\text{C}_4\text{H}_{10} + \text{Cl}_2 \rightarrow \text{C}_4\text{H}_8\text{Cl}_2 + \text{H}_2$
  • B$\text{C}_4\text{H}_{10} + \text{Cl}_2 \rightarrow \text{C}_4\text{H}_9\text{Cl} + \text{HCl}$
  • C$\text{C}_4\text{H}_{10} + \text{Cl}_2 \rightarrow 2\text{C}_2\text{H}_5\text{Cl} + \text{H}_2$
  • D$\text{C}_4\text{H}_{10} + \text{Cl}_2 \rightarrow \text{C}_2\text{H}_4 + \text{C}_2\text{H}_5\text{Cl} + \text{HCl}$
