    When alkyl halide reacts with aqueous sodium hydroxide to give alcohol, the reaction is called

    A)  electrophilic substitution

    B)  nucleophilic substitution

    C)  free radical substitution

    D)  None of the above

    Correct Answer: B

    Solution :

                     When alkyl halide reacts with aqueous \[NaOH\] then alcohol is formed.                 \[R-X+NaOH\xrightarrow{{}}ROH+NaX\] In this reaction \[O{{H}^{-}}\] is a nucleophile and it replaces the halogen as halide. Therefore, this reaction is called nucleophilic substitution reaction. Note-\[R-X+{{Z}^{-}}\] (nucleophile) \[\xrightarrow{{}}R-Z+{{X}^{-}}\]
