    The high oxidising power of fluorine in due to Its

    A)  high electron affinity

    B) high heat of dissociation and low heat of hydration

    C)  low heat of dissociation and high heat of hydration

    D) high heat of dissociation and high heat of hydration

    Correct Answer: C

    Solution :

    The high oxidising power of fluorine is due to its low heat of dissociation and high heat of hydration. Due to its smallest size, there is considerable repulsion in the non-bonding electrons which weakens the F?F bond. Thus, bond dissociation energy of \[C{{H}_{3}}\]is low.
