Which alkyl halide undergoes E2 elimination at the fastest rate?
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The ease of reaction is: t-alkyl halide > s-alkyl halide > p-alkyl halide So tertiary alkyl halide will undergo the reaction the fastest. Furthermore, A will undergro E2 elimination at a faster rate because Br -is a better leaving group than Cl-

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
