As we learnt in 

Acidic strength of Hydride -

HI>HBr>HCl>HF

- wherein

Increases down the group 

 

Dipole moment of Hydride -

HF>HCl>HBr>HI

- wherein

Deacreses due to decrease in electronegativity difference 

 

Dipole moment is maximum when electronegative difference is maximum i.e. in case of HF.

Ionization constant of HI>HF as it's value increases down the group due to weakening of bond.
