Vedclass · Answer

(B) The reaction of an ether with concentrated $HI$ involves the protonation of the ether oxygen followed by nucleophilic attack by the iodide ion $(I^-)$.In the given ether,$CH_3-O-CH_2Ph$ (benzyl methyl ether),the protonation occurs at the oxygen atom.The iodide ion $(I^-)$ attacks the less sterically hindered carbon atom,which is the methyl group $(CH_3)$,via an $S_N2$ mechanism.This leads to the formation of $CH_3I$ (methyl iodide) and $PhCH_2OH$ (benzyl alcohol).Therefore,the products $A$ and $B$ are $MeI$ and $PhCH_2OH$.
