benzene is less reactive than toluene towardselectrophilic substitution reactions because in toluene mehyl groupdonates electrons inductively to the benzene ring and activates ittowards electrophilic substitution but in case of nitromethylbenzene the electron donating capacity is decreased because nitrogroup is strongly electron withdrawing and will with drawelectrondensity.
