Question

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

Solution

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.
