inductive effect of halogen is more pronounced than resonance effect,so will be the acidity.As inductive effect depend on the distance,so ortho will be most acidic and para will have least acidity

F is more electro negative than Cl . Bcz –I effect of F is greater than Cl ..... To phir , p-fluoro phenol should be more acidic than p-chloro phenol. But the actual order is reversed . This reversed behavior arises due to the delocalization of negative charge of oxygen atom in both compound Lekin....In case of p-chloro phenol , the negative charge on oxygen atom delocalized to the vacant d-orbital of - Cl atom present in the para-position . But this is not possible for p-fluoro phenol . Bcz -F atom has no vacant d-orbital . Thus the conjugate base of p-chloro phenol is more stable than p-fluoro phenol . To phir..... p-chloro phenol more acidic than p-fluoro phenol .
