Identify !!Y!! and !!Z!! of the following reaction:
(a) !!Y= C_2H_5I, Z= C_6H_5CHO!!
(b) !!Y= C_6H_5I, Z= C_2H_5OH!!
(c) !! Y= C_6H_5OH, Z= C_2H_5I!!
(d) !!Y= C_6H_5OH, Z= CH_3CH_3 !!
The phenyl-O bond has a partial double bond character, which is difficult to break. Therefore, it remains the same.
Products are !! Y= C_6H_5OH, Z= C_2H_5I!!.
In case If we are able to break the phenyl-O bond, then it would have result in !!Ph^+!!, which is highly unstable.
Therefore correct answer is (c).
