Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Here it written that ortho cresol has field effect but it should be inductive effect...more the inductive effect lesser the acidity cresol i andp-cresols. out
OJugation effect like resonance effect (as discussed under nitrphcnols) cannot opCrate at m-position ucrctorC, m-cresol is more acidic than o- andp-cresols. Out of o-and p-cresols, p-cresol is Inore acidic than o-cresol due to field effect which makes the loss of a proton little more difficult. Thus, the overall acidic strength of cresols relative to phenols decreascs in the order Phenol> m-Cresolp-Cresol >o-Cresol Conaen

CH3 group being nearer to phenol group in ortho leads to increase in electron density and thus destabilization of conjugate base leading to a weaker acid. Come to your doubt.... generally whenever inductive effect arises it is also experienced as field effect..but in certain cases for bigger molecules field effect has little bit more clarity than inductive effect...so here due to inductive effect the conjugate base destabilizes also written as field effect.

Ortho and para both have Hyperconjugation while meta have only +I effect so meta is least Acidic than ortho and para. not in case of O and p cresol we will compir by inductive effect o-cresol have less distance of Me group so more +I and hence less Acidic than p-cresol which have me group at para so more distant and less +I effect
