Question

increasing order of acidic character HF HCl HBr HI

Answer 1

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. acid strength order is HF > HCl > HBr > HI. As one goes down the group, the atomic size increases and electronegativity decreases.

Answer 2

increasing order of acidic strength is HF<HCl< HBr<HI
