When $o-$bromoanisole is treated with $NaN{H}_2$ in $N{H}_3(l),$ a reaction proceeding via a benzyne intermediate, what two isomeric products are possible? $($Check two products$).$

$m-$methoxyaniline

p$-$methoxyaniline

$o-$methoxyaniline

In practice, only one isomer forms. Which isomer forms?

$m-$methoxyaniline

$o-$methoxyaniline

p$-$methoxyaniline
