Vedclass · Answer

(A) This is an example of a nucleophilic aromatic substitution reaction. The electron-withdrawing $-NO_2$ group at the para position activates the ring towards nucleophilic attack. The nucleophile $C_2H_5O^-$ attacks the carbon atom bearing the bromine atom at the para position relative to the $-NO_2$ group,as it is more sterically accessible and electronically activated. Thus,the bromine atom at the para position is replaced by the $-OC_2H_5$ group,resulting in $1-bromo-2-ethoxy-4-nitrobenzene$.
