Vedclass · Answer

(A) The reactivity of benzene derivatives towards electrophilic substitution depends on the electron density of the ring.Groups that increase electron density (activating groups) increase reactivity,while groups that decrease electron density (deactivating groups) decrease reactivity.$1$. $-CH_3$ (in $B$) is an electron-donating group due to the $+I$ effect and hyperconjugation,making it more reactive than benzene $(A)$.$2$. Benzene $(A)$ is the reference compound.$3$. $-Cl$ (in $C$) is deactivating due to its strong $-I$ effect,which outweighs its $+M$ effect,making it less reactive than benzene.$4$. $-NO_2$ (in $D$) is a strongly deactivating group due to both $-I$ and $-M$ effects,making it the least reactive.Therefore,the correct order of reactivity is $B > A > C > D$.

In the given compounds,the correct order of reactivity in electrophilic substitution reactions will be:
