Ortho effect is a special type of effect that is shown by o-substituents, but it is not necessarily just a steric effect. This ortho-effect operates with  the benzoic acids. Irrespective of the polar type nearly all o-substituted benzoic acid are stronger than unsubstituted benzoic acid. Benzoic acid is a resonance hybrid and so the carboxyl group is coplanar with the ring. An o-substitueut tends to prevent this coplanarity. Ortho effect also operates in substituted anilines where as ortho substituent has base weakening effect.
Q. What is the order of acidity of following compounds :
  • a)
    I > IV > III > II  
  • b)
    I > III > IV > III  
  • c)
    IV > I > III > II
  • d)
    III > IV > I > II
Correct answer is option 'A'. Can you explain this answer?
