            Which of the following compounds will be more easily attacked by an electrophile?            

A)                        

B)                                            

C)                            

D)                        

Correct Answer: C

Solution :

                ?CI is able to deactivate the benzene nucleus but show o/p-directive influence while ?OH and \[-C{{H}_{3}}\] activate the benzene nucleus (order \[-OH>-C{{H}_{3}}\]) so, they show electrophilic substitution easily on o/p position in comparison to benzene.                 Order of electrophilic substitution                 Thus phenol will be most easily attacked by an electrophile.
