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

Explanation

Chemically both sect are equallly . It set ()A the Br group is activated by the electron withdrawing effect of `-NO_(2)` group. Therefore, nucleophilic attack of `CH_(3)ONa` followed by elimination of NaBr gives the desired ether.


In set (B), nucleophilic attack of 4-nitrophenoxide ion an methyl bromide gives the desired product.
