    In paraffins, with the increasing molecular weight, it is found that [CPMT 1974]

    A) Freezing point decreases

    B) Boiling point decreases

    C) Boiling point increases

    D) Vapour pressure decreases

    Correct Answer: C

    Solution :

    Paraffins are non-polar compounds. The intermolecular forces are weak Vander Waal?s forces.  As the molecular mass increases Vander Waal?s forces increases. Hence boiling point increases.
