Question

Imagine that a scientist mixes bromoethane and potassium iodide in methanol. What type of reaction is likely to predominate? Remember to consider the type of alkyl halide that is involved, and remember also to consider whether the anion will act predominantly as a base or as a nucleophile or as both a base and a nucleophile. If the latter, consider the figure below to guide your decision. Finally, remember to consider the ΔpKa rule, as it applies to each of the various reaction archetypes. SN2 E2 10 30 2° Type of Alkyl Halide mostly Sy1 with some 1 predominantly SN2 predominantly E1cB O predominantly E1 O predominantly SN1 O mostly E2 with some SN2 mostly E1 with some SN1 predominantly E2 mostly Sy2 with some E2 O O
