Question

explain the strength of acids increase in order :HI >HBr >HCl >HF​

Answer 1

Answer:

HCl, HBr, and HI are all strong acids, whereas HF is a weak acid. The acid strength increases as the experimental pKa values decrease in the following order: HF (pKa = 3.1) < HCl (pKa = -6.0) < HBr (pKa = -9.0) < HI (pKa = -9.5). ... Shorter bonds are more stable, and thus the H-F bond is more difficult to break.

Answer 2

Answer:

Size factor

Explanation:

HI has larges rise due to which there is weak bonding so H+ is easily released.
