Firstly, +I grps- all methyl groups and those groups with a negative charge Then , -I effect - all functional groups and all groups with a positive charge. +M effect- groups which have lone pairs (also incld functional groups with lone pairs) , all methyl grps (due to hyperconjugation), groups with a negative charge -M groups- groups with positive charge, functional groups with no lone pair(eg NO2) Remember - halogens show +m effect and -I effect but their -i effect is more dominating while in other functional groups +M is more dominating if they show +M and -I ( -OCH3)

Ortho Para directing group hai OH( +M dega) toh tum agar ortho para p EDG lagaoge toh repulsion start hojayega aur phenoxide ion unstable hojayega Aur agar EWG lagaoge toh phenoxide ion jyada stable hoga because of the presence of partial negative charge on ortho and para of hybrid structure of phenoxide ion....

31:30 onwards... Inductive effect depends on distance...and at meta position only inductive effect is functional...so in questions of arranging in order of acidic strength in case of effect of substituents on phenol, inductive effect must be given priority over mesomeric effect at meta position.
