Question

which is the strongest acid hydrogen halide? give reasons X=F, Cl, Br, I​

Answer 1

HI will be the strongest acid..as the size of iodine is biggest compared to all halogen.. it will be least electronegative and the bond breaking of HI bond will be easier.. HF will be the weakest acid as the polarising ability of fluorine is the highest and bond breaking of HF requires a huge amount of energy....

Answer 2

Answer:

HI is the strongest acid....

The order of acidic character can be explained in terms of strength of H-X* bonds, which is in the order H-I< H-Br < H-Cl < H-F.

Since H-I bond is weakest, therefore, HI is the strongest acid.
