Arrange the following in the order of reactivity of their electrophilic addition reaction:
HI,HF,HCl,HBr
HI>HBr>HCl>HF
HF>HCl>HBr>HI
HCl>HF>HBr>HI
HF>HBr>HI>HCl
Towards electrophilic addition reaction reactivity order is
This order follows the order of acidic strenght of the hydrogen halide.
Hence, the correct answer is Option (1)
