This is due to the increase in the size of the halogen atom and the decrease in the strength of the hydrogen bond as the electronegativity of the element decreases. Therefore, the boiling point trend is: HF > HCl > HBr > HI. jobs in pinetown area

"WebAug 21, 2024 · In H 2 O solution, hydrofluoric acid (HF) is a weak acid. Although fluorine is highly electronegative, its electronegativity does not determine its acidity; HF is a weak acid due to the fact that the fluoride ion is basic (pH>7). In addition, fluorine produces very powerful oxidants. ... The melting and boiling points increase down the group ... " - Boiling point of hf acid
