    Which one among the following is most reactive towards electrophilic substitution reaction?

    A)  Aniline                                

    B)  Nitrobenzene

    C)  Benzoicacid     

    D)  Acetanilide

    Correct Answer: A

    Solution :

                    The activating substituents make the benzene ring more reactive towards electrophilic substitution reaction while the deactivating substituents make the benzene ring less reactive towards electrophilic substitution reaction.\[N{{H}_{2}}\]group is the most activating group which is present in aniline\[({{C}_{6}}{{H}_{5}}-N{{H}_{2}})\]hence it is the most reactive towards electrophilic substitution reaction.
