    Which one of the following is the most reactive towards ring nitration?

    A)  Benzene           

    B)  Mesitylene

    C)  Toluene            

    D)  m-xylene

    Correct Answer: B

    Solution :

                    Mesitylene (1, 3, 5-trimethyl benzene) has three, m-xylene (1, 3-dimethylbenzene) has two while toluene has only one electron donating \[II<\text{ }III<I<IV\] group. Therefore, electron density is maximum in mesitylene and hence, it is most reactive towards ring nitration.
