Detailed Solution

Given data:
It is given to identify the compound when phenolic ether is heated with HI.
Explanation:
Due to the more stable aryl-oxygen bond, alkyl aryl ethers are cleaved at the alkyl-oxygen bond. As a result, protonation of anisole produces the first methylphenyl oxonium ion in the case of anisole. Compared to the link between oxygen and hydrogen, the oxygen-methyl bond is weaker. As a result, phenol and methyl iodide are produced by the iodide ion's assault.
