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

Answer»

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.

Thanks!
