Toluene

Vedclass · Answer

(C) The order of reactivity towards electrophilic aromatic substitution is governed by the presence of electron-donating or electron-withdrawing groups attached to the benzene ring.$Toluene$ contains a methyl group $(-CH_3)$,which is an electron-donating group due to hyperconjugation and the inductive effect,making the ring more reactive towards electrophiles.$Benzene$ is the standard reference.$Nitrobenzene$ $(C_6H_5NO_2)$ has a strongly electron-withdrawing nitro group $(-NO_2)$,which deactivates the ring.$Chlorobenzene$ has a chloro group $(-Cl)$,which is deactivating due to its strong $-I$ effect.Thus,$Toluene$ is the most reactive towards nitration.
