Vedclass · Answer

(B) The reaction involves a nucleophilic aromatic substitution $(S_NAr)$ mechanism. $2$ moles of $1$-chloro-$4$-nitrobenzene react with $Na_2S$. The sulfide ion $(S^{2-})$ acts as a nucleophile and attacks the electrophilic carbon attached to the chlorine atom in $1$-chloro-$4$-nitrobenzene,displacing the chloride ion. This forms a $4$-nitrobenzenethiolate intermediate,which then reacts with another molecule of $1$-chloro-$4$-nitrobenzene to form the final product,Bis($4$-nitrophenyl) sulfide.
