OH is a stronger ortho and para director then Cl. Cl is an ortho, para director but is ring deactivating.

OH groupe has +M&-I effect but +M > > -I
+M means that (OH) groupe direct the resonance against it by electron lone pair on the o-atom.
-I (INDUCTIF EFFECT throw segma bond OH electron withdrawing group)SO,it's ortho & para activate directing groupe.
CL has -I >>+M SO it's ortho & para deactivate directing groupe .
(finally OH stronger ortho & para directing groupe than CL.

I think Cl- is. Its easy to produce chlorine-saturated benzene, HCB. Is the same so for a hexahydroxy-benzene?
