    Reaction of methyl bromide with aqueous sodium hydroxide involves

    A) racemization

    B) \[{{S}_{N}}1\] mechanism

    C) retention of configuration

    D) \[{{S}_{N}}2\] mechanism

    Correct Answer: D

    Solution :

    \[\xrightarrow{{}}HOC{{H}_{3}}+B{{r}^{-}}\] Since, the reaction rate depends upon the concentration of both reactant and nucleophile, it is a \[{{S}_{N}}2\] reaction. It involves inversion of configuration.
