    y the strength of hydrogen halogen bond decreases with increase in size of halogen atom?while their melting pt. and boilig pt. increases down the group..they must also decrease if strength of bond decrease?

    Boiling point and melting point depend on intermolecular forces. HF has a higher boiling pt than other hydrogen halides because of strong hydrogen bonding. From hydrogen chloride to hydrogen iodide, boiling point increases because of stronger london dispersion forces. London dispersion forces increase with increasing molecular mass. Hope this helps!
