HI is the strongest acid as it forms weak overlap with 1s orbital of hydrogen resulting in loose of H+ easily.

Dear,

bond dissociation energy with hydrogen decreased down the group so HI is will be the most reactive .

Thanks and Regards

As electro negativty is of the order F>Cl>Br >I but when these are bondrmed with hydrogen , acidic character follows the order HI>HBr>HCl>HF so HI is more reactive than any other ,as well as it is a strong reducing agent .This might be the reason....

Hello Student,

HI is more reative because the bond dissociation energy is low due to difference in size of hydrogen and iodine so it can be easily breaked.

Order: HI>HBr>HI

Dear,HI most reactive amongst them because iodine has larger radii as compared to hydrogen and due bond length is also very large due to this the attraction between two atom is less since easily the bond can be broken as the bond dissociation energy is also less hence it can easily react
