Question

Quizplus · Accepted Answer

The transformation involves a substitution reaction where a primary alcohol is being converted into an alkyl chloride. The reagent for this conversion is usually SOCl2 or PCl5, which can directly convert the alcohol into the corresponding chloride. However, in this case, the alcohol is attached to a double bond, which makes it less reactive towards nucleophilic substitution. To overcome this difficulty, the alcohol can be first treated with NaNO2 and HCl to form the corresponding diazonium salt, which can then be reacted with NaI to give the desired alkyl iodide. Therefore, the best choice for this transformation is option B, which involves the use of NaN02 and HCl followed by NaI.
