Vedclass · Answer

(D) Electrophilic substitution reactions are favored by electron-donating groups $(EDG)$ and hindered by electron-withdrawing groups $(EWG)$.$NO_2$ is a strong electron-withdrawing group due to both $-I$ and $-M$ effects.In all three isomers ($m-$,$p-$,and $o-$ dinitrobenzene),there are two $NO_2$ groups attached to the benzene ring,which significantly deactivate the ring toward electrophilic attack.However,the reactivity depends on the net electron density on the ring. In $m-dinitrobenzene$,the $NO_2$ groups are at positions $1$ and $3$. In $p-dinitrobenzene$,they are at $1$ and $4$,and in $o-dinitrobenzene$,they are at $1$ and $2$.Since all three compounds are highly deactivated by two strong EWGs,they are all extremely unreactive toward electrophilic substitution. In the context of standard chemistry problems,when comparing these specific isomers,they are often considered to have negligible reactivity compared to benzene or substituted benzenes with EDGs. Given the options,they are effectively equally unreactive.

Which of the following compounds is most reactive toward electrophilic substitution reaction?
