Question

Which of the following is an appropriate set of reactants for the preparation of 1-methoxy-4-nitrobenzene?

• A. $\left(i\right)$
• B. $\left(ii\right)$
• C. Both $\left(i\right)$ and $\left(ii\right)$
• D. None of these

Answer 1

The correct option is B $\left(ii\right)$

1-methoxy-4-nitro benzene

Phenoxide ion attack the methyl bromide to give the the product 1-methoxy-4-nitrobenzene in a ${SN}_2$ manner.

In first case the $C{H}_{3}ONa$ will acts as base so elimination is preferred over substitution.
