The heating of phenyl-methyl ethers with HI produces

1. Iodobenzene
2. Phenol
3. Benzene
4. Ethyl chlorides

Correct answer: Phenol

Solution

When phenyl-methyl ether reacts with HI, the bond between the oxygen and methyl group breaks, forming phenol and methyl iodide. This is a standard reaction of ethers with HI.
