Question

Quizplus · Accepted Answer

This transformation involves converting an alkyl bromide to an alkyl chloride. One common method for this conversion is to react the alkyl bromide with sodium nitrite in hydrochloric acid to form the corresponding diazonium salt, which can then be treated with sodium iodide to form the alkyl chloride. Choice B provides both the sodium nitrite/HCl reagent and the sodium iodide reagent needed for this transformation. Choices A, C, and D do not provide both reagents needed for this specific transformation.
