Which of the following alkyl halides is NOT suitable for preparing alkanes via Corey-House synthesis — Hydrocarbons Chemistry Question

💡 Solution & Explanation

In the Corey-House synthesis, the alkyl halide reacting with the Gilman reagent ($R_2CuLi$) must be methyl or primary ($1^\circ$). A tertiary halide like tert-butyl bromide undergoes E2 elimination instead.
