Which alkyl halide from each of the given pairs reacts more rapidly in an elimination reaction? Provide a short explanation of your answer.

• A. (a) (i) can undergo elimination more rapidly due to the stronger leaving group.
  (b) Only (i) can undergo elimination reaction because (ii) lacks any axial hydrogen at a β-carbon.
• B. (a) (ii) can undergo elimination more rapidly due to the stronger leaving group.
  (b) (ii) can undergo elimination reaction more rapidly because of the less steric hindrance.
• C. (a) (ii) can undergo elimination more rapidly due to the stronger leaving group.
  (b) Only (i) can undergo elimination reaction because (ii) lacks any axial hydrogen at a β-carbon.
• D. (a) Both structures have the same reactivity towards an elimination reaction.
  (b) Only (ii) can undergo elimination reaction because (i) lacks any equatorial hydrogen at a β-carbon.

Answer: (C)
