Isopropyl methyl ether when treated with cold hydrogen iodide gives:(a) isopropyl iodide and methyl iodide(b) isopropyl alcohol and methyl iodide(c) isopropyl alcohol and methyl alcohol(d) isopropyl iodide and methyl alcohol

When isopropyl methyl ether (also known as 2-methoxypropane) is treated with cold hydrogen iodide (HI), it undergoes a nucleophilic substitution reaction known as the Williamson ether synthesis. In this reaction, the ether oxygen is replaced by an iodine atom. The product formed depends on the specific conditions and reagents used.

The correct answer is:
(a) Isopropyl iodide and methyl iodide

The reaction can be represented as follows:

Isopropyl methyl ether + HI → Isopropyl iodide + Methyl iodide
