Question

Why the acidic strength of halogen acids increases in order hf-hcl-hi?

Answer 1

Electronegativity is the ability of an atom to pull electrons towards itself.acid strength order is HF > HCl > HBr >HI. As one goes down the group, the atomic size increases and electronegativity decreases. Electronegativity is the ability of an atom to pull electrons towards itself.

Answer 2

Answer:

Explanation:

if you remove hydrogen from all you f-, cl- and i-

negative charge on more electronegative atom is more stable

so hf>hcl>hi
