    The correct order of reactivity of halogens is [MHCET 2003]

    A) \[F>Cl>Br>I\]

    B) \[F<Cl>Br<I\]

    C) \[F<Cl<Br<I\]

    D) \[F<Cl<Br>I\]

    Correct Answer: A

    Solution :

    We know that atomic no. of fluorine (F), chlorine (Cl), Bromine (Br) and Iodine (I) are 9, 17, 35 and 53 respectively. Therefore correct reactivity of halogens is \[F>Cl>Br>I\]
