Interpretation Introduction

Interpretation:

The structure having a molecular formula ${\text{C}}_{\text{8}}{\text{H}}_{\text{7}}{\text{Br}}_{\text{2}}{\text{NO}}_{\text{3}}$ that is prepared during the reaction of $1,2,3-\text{tribromo}-5-\text{nitrobenzene}$ with sodium ethoxide is to be determined.

Concept introduction:

Nucleophilic aromatic substitution reactions involve the substitution of a leaving group by an upcoming nucleophile.

The aromatic ring is itself act as a nucleophile, hence the ring undergoes this substitution only in the presence of a strong electron withdrawing so that it stabilized the negative charge on the ring.
