sir.....so aryl halides never show resonance ....
overlapping is most deciding factor for inductive effect dominance...but aryl halide show +R effect due to lone pairs on halogen atom
overlapping to resonance main bhi Hoti hai
Halogens electronegative bhi hote hai so electrons withdraw krte hai ...show-I effect
