Which of the following is an appropriate set of reacnts for the preparation of 1-methoxy-4 nitrobenzne and why ?

Explanation

The second set of reactants is more appropriate to give the products i.e., 1-methoxy-4 nitrobenzene. In the first set cleavage of C-Br bond is involved. It is rather difficult since the carbon atom is `sp^(3)` hybridised and the bond has partial double bond charachter as well. The product is formed as a result of Williamson's synthesis.
