An aromatic ether is not cleaved by $HI$ even at $525 \ K$. The compound is

Allyl phenyl ether can be prepared by heating:

An organic compound with the molecular formula $C_4H_{10}O$ does not react with sodium metal. Upon reaction with excess $HI$,it yields only two types of halides. Identify the compound.

Which of the following products is formed when ether is exposed to air?

Describe the nucleophilic reactions of ethers with $HX$ and provide examples.

Match the starting materials given in Column-$I$ with the products formed by these (Column-$II$) in the reaction with $HI$.
