    \[C{{H}_{2}}Br+\bar{O}H\xrightarrow{{}}C{{H}_{3}}OH+B{{r}^{-}}\]reaction proceeds by\[{{S}_{N}}2-\]mechanism. Its rate is dependent on the concentration of

    A) \[C{{H}_{3}}Br,\bar{O}H\]

    B) \[C{{H}_{3}}Br\]only

    C) \[~\bar{O}H\] only     

    D) \[~C{{H}_{3}}Br,C{{H}_{3}}OH\]

    Correct Answer: A

    Solution :

     \[C{{H}_{3}}Br+O{{H}^{-}}\xrightarrow{{}}C{{H}_{3}}OH+B{{r}^{-}}\] This reaction proceeds by \[{{\text{S}}_{\text{.N}}}\text{2}-\]mechanism Rate \[\propto \][substrate] [nucleophile]      Rate \[\propto [C{{H}_{3}}Br][O{{H}^{-}}]\]
