HCl, HBr, HI, etc.

[Michael Du 1E]

Is the reasoning behind HCl, HBr, etc. being a strong acid is that its anion is stable? if not whats the particular reasoning behind why they are strong acids? thank you!

[Anish Patel 4B]

YEs since fluorine is the most electronegative, it has the highest electron withdrawing ability making the molecule more stable and less able to dissociate its H+ ions in water.

[Kassidy Ford 1I]

You can also think of it in terms of bond length; since the bond between H-I is the longest it is the strongest acid because that bond will be easier to break, so it will dissociate the easiest. HI>HBr>HCl>HF. HF is a weak acid because F's high electronegativity and small size makes that bond short and strong so it will not break easy and it will not dissociate fully.
