Answers
Question :-
why halogens substituted on benzene ring are Ortho para directorband not meta director ? Explain.
Answer :-
Halogens are very electronegative. This means that inductively they are electron withdrawing. However, because of their ability to donate a lone pair of electrons in resonance forms, they are activators and ortho/para directing. Resonance forms win out in directing. Because they are electron withdrawing, halogens are very weak activators.
