Vedclass · Answer

(B) The reaction of an alkyl aryl ether with $HI$ involves the protonation of the ether oxygen atom followed by the nucleophilic attack of the iodide ion $(I^-)$ on the less sterically hindered alkyl group.In $1-$methoxy naphthalene,the oxygen is attached to a methyl group and a naphthyl group.The $I^-$ ion attacks the methyl group $(CH_3)$ via an $S_N2$ mechanism because the naphthyl group is bulky and the $C-O$ bond involving the aromatic ring has partial double bond character,making it resistant to nucleophilic substitution.Thus,the products formed are $CH_3I$ (methyl iodide) and $1-$naphthol.

Main products formed during a reaction of $1-$methoxy naphthalene with hydroiodic acid are:
