    check the pka values correct order is 1>2>3>4. 1 is most acidic because of ortho effect.. Now we will check the -I effect of F at meta and para position. -I effect is maximum at meta and less on para so meta is more acidic than para. there is no effect in benzoic acid.. so overall acidity order is 1>2>3>4

    Acidity order 1>2>3>4. ortho fluoro benzoic acid is most acidic here due to ortho effect and benzoic acid is least acidic.. For halogen only inductive effect works and inductive effect decrease with distance so 2>3 ... overall order 1>2>3>4
