    Boiling point of alcohol is comparatively higher than that of corresponding alkane due to

    A) intermolecular hydrogen bonding

    B) intramolecular hydrogen bonding

    C) volatile nature

    D) None of the above

    Correct Answer: A

    Solution :

    Because of intermolecular hydrogen bonding in alcohols, they exist as associated molecule. Consequently, a large amount of energy is required to break these bonds and, therefore, their boiling points are higher than that of the corresponding hydrocarbons (hydrogen bonding is absent in hydrocarbons).
