How many groups are of o/p director in the electrophilic aromatic substitution ?

Ortho and para directing groups are  :-

• O⁻, −OH, −OR, −NH₂​, −NHR, −NR₂​, OOR, NOR, −CH₃​ , alkyl group, −SH, −SR, −F, −Cl, −Br, −I
• Ortho and para directing groups give ortho  and para substituents as major products and meta directing as minor products 
• Also, activating groups increase the rate of electrophile aromatic substitution, relative  to hydrogen.
