Question

Diethyl ether on heating with excess conc.HI givee

Answer 1

Answer:

When diethyl ether is heated with excess of HI is Ethyl iodide only. The reaction is explained below : ... - And when present in excess the ethyl alcohol formed under reaction with HI is further to give ethyl iodide.

Explanation:

Ether react with hydroiodic acid to form alcohols and corresponding haloalkanes. When present in excess the alcohol formed under reaction with HI further to give haloalkane

Ethers can be cleaved by HI because it is sufficiently acidic to protonate ethers. Note: The order of reactivity of hydrogen halides is HI>HBr>HCl. In this reaction, diethyl ethers when reacts with concentrated HI, it gives two molecules of alkyl halide.
