    O-fluorophenol is more acidic than p-fluorophenol. This is because fluorine is more electronegative than oxygen and when both the conjugate bases are formed the negative charge on oxygen is more stabilised by ortho fluorine than by para fluorine due to lesser distance and hence greater inductive effect. Hence more stable conjugate base produces more acidic acid.

    sir in this case is +R or -I we have to prefer
