Question

Alkyl iodide can be obtained from alcohol
using one of the following reagents. Identify
the reagents.
(A) Red P, lodine
(B) conc. HNO3, HI
(C) conc. HCI, HI
(D) ZnCl2, HI​

Answer 1

Answer:

(a) Red Phosphorus/Iodine

Explanation:

In general, using P/X₂ or PX₃ or PX₅ with an alcohol gives the respective alkyl halide (where X stands for any halogen). So, using red phosphorus and iodine will yield alkyl halide.

Note: ZnCl₂/HCl is called Lucas reagent which produces alkyl chloride when reacted with alcohol. But here, you want alkyl iodide and using HI with ZnCl₂ will not produce alkyl iodide.
