    Explain why the boiling point of hydrogen bromide lies between those of hydrogen chloride and hydrogen iodide

    FIRST i thought polar-molecules but they all are, then I thought electronegativity but that would contradict the boiling points

    I said because Bromide is a smaller molecule than iodide therefore less electrons and weaker van de Waals forces on the other hand it is a larger molecule than chloride atom therefore more electrons and stronger van der waals forces.

    So it was right to talk about van de Waals?
    I knew it!

    Explain why the boiling points of HBr is lower than HI but higher than HCL?

    HI is a larger molecule (has more electrons) than HBr and therefore has more/stronger forces of van der waals so more energy is required to break these bonds thats why it has a higher boiling point. Opposite reasoning for HCl.
