Detailed Solution

Halo group shows +M effect by donating $' l p'$

But +M effect of -Cl, -Br, -I is

very poor because

3P-2P overlap of Cl - carbon

4P-2P overlap of Br - carbon

5P-2P overlap of I - carbon is very poor

-X group shows -I effect

In halo arenes -I > +M

In halo arene -Inductive deffect decides reactivity

+M effect decides orientation

$∴ C_{6} H_{5} X$ is less reactive than benzene

towards ESR but it is an o, p-directing group

-X is deactivity and o, p-directing group
