    HI is most Acidic. HF < HCl < HBr < HI Down the group the electronegativity decreases and the size increases. Thus, it becomes easy to lose H + ion. This causes the increase in acidic strength down the group.

    HI Since H−I bond is weakest and has a low bond dissociation energy so it can give H+ ion easily, therefore, HI is the strongest acid. On the other hand H-F bond is strongest, hence it is the weakest acid among all the halogen acids.
