Which one is most reactive towards electrophonic reagent?

A)                                                

B)  

C)                                                

D)  

Correct Answer: A

Solution :

Key Idea Electron withdrawing substituent deactivates the benzene nucleus towards electrophonic substitution while electron releasing substituent   activates   the   ring   towards electrophonic substitution. Among the given,?OH has the higher electron donating tendency and thus, activates the ring more towards electrophonic substitution. Hence, is more reactive towards electrophonic reagent.
