Dear Sourav...In case of fluorophenol the H bonding is not much pronounced...So here you see acidity only by -I effect of fluorine as also we see generally inductive effect of halogen group.
orthofluoro phenoxide ion will be stabilized by electron withdrawing effect of F atom present nearby. Whereas in meta and para isomer as the distance increases stabilization of phenoxide decreases. Therefore acidity decreases.
sir but it is given due to H bonding in Fluoro phenol, reso is not seen
No you see various various explanations everywhere...just differentiate these things and make your own key concept for remembering this
Just keep in mind here H bonding is not much pronounced so inductive effect decides acidity
