Vedclass · Answer

(A) The reactivity of benzene derivatives towards electrophilic aromatic substitution depends on the electron density of the benzene ring.Electron-donating groups $(EDG)$ increase reactivity, while electron-withdrawing groups $(EWG)$ decrease it.$1$. In $c$ (Anisole, $C_6H_5OCH_3$), the $-OCH_3$ group is a strong electron-donating group via the $+M$ effect, which significantly increases the electron density of the ring.$2$. In $a$ (Chlorobenzene, $C_6H_5Cl$), the $-Cl$ group is an electron-withdrawing group via the $-I$ effect, though it is ortho/para directing due to the $+M$ effect. Overall, it deactivates the ring compared to benzene.$3$. In $b$ (Nitrobenzene, $C_6H_5NO_2$), the $-NO_2$ group is a very strong electron-withdrawing group via both $-I$ and $-M$ effects, which strongly deactivates the ring.Therefore, the increasing order of reactivity is: $b$ (most deactivated) $The correct order is $b < a < c$.

Consider the following compounds:
$a$: Chlorobenzene
$b$: Nitrobenzene
$c$: Anisole
Arrange these compounds in the increasing order of reactivity towards electrophilic aromatic substitution (nitration).
