    The general reaction, \[R-X\xrightarrow{aq.OH-}ROH+{{X}^{-}}\] is expected to follow decreasing order of reactivity as in

    A) \[t-BuI>t-BuBr>t-BuCl>t-BuF\]

    B) \[t-BuF>t-BuCl>t-BuBr>t-BuI\]

    C) \[t-BuBr>t-BuCl>t-BuI>t-BuF\]

    D) \[t-BuF>t-BuCl>t-BuI>t-BuBr\] (t-Bu = tertiary Butyl group)

    Correct Answer: A

    Solution :

    The order of reactivity of alkyl halides: iodide > bromide > chloride (nature of the halogen atom) tertiary > secondary > primary (type of halogen atom).
