Vedclass · Answer

(C) The reactivity of benzene derivatives towards electrophilic substitution depends on the nature of the substituent group attached to the benzene ring.Electron-donating groups $(EDG)$ increase the electron density of the ring,making it more reactive,while electron-withdrawing groups $(EWG)$ decrease the electron density,making it less reactive.$1$. Benzene $(1)$: Reference compound.$2$. Toluene $(2)$: The $-CH_3$ group is an electron-donating group due to the $+I$ effect and hyperconjugation,which increases the reactivity compared to benzene.$3$. Chlorobenzene $(3)$: The $-Cl$ group is deactivating due to its strong $-I$ effect,although it is ortho/para directing due to resonance ($+M$ effect). Overall,it is less reactive than benzene.$4$. Nitrobenzene $(4)$: The $-NO_2$ group is a strong electron-withdrawing group due to both $-I$ and $-M$ effects,significantly reducing the electron density of the ring and making it the least reactive.Therefore,the correct order of reactivity is $2 > 1 > 3 > 4$.
