Vedclass · Answer

(D) The reaction of an ether with $HI$ involves the protonation of the ether oxygen atom to form an oxonium ion. In the case of $Ph-O-CH_2-Ph$,the cleavage occurs such that the more stable carbocation is formed. The $Ph-CH_2^+$ (benzyl carbocation) is stabilized by resonance,whereas the $Ph^+$ (phenyl carbocation) is highly unstable. Therefore,the $I^-$ ion attacks the $CH_2$ group of the benzyl moiety,leading to the formation of $Ph-OH$ and $Ph-CH_2-I$.
