    Consider the following statements in respect of the reaction
    \[{{(C{{H}_{3}})}_{3}}CBr+\bar{O}H\xrightarrow{\text{Alcohol}}\,\,{{(C{{H}_{3}})}_{3}}COH+B{{r}^{-}}\]
    1. It is a nucleophilic substitution.
    2. It is a two-step reaction.
    3. The rate of the reaction depends only on the concentration of the alkyl halide.
    4. It is an \[{{S}_{N}}2\] reaction.
    5. Carbocation intermediate is formed in this reaction.
    Which of the above statements are correct?

    A) 1, 2, 3 and 5     

    B) 1, 2 and 5 only

    C) 3 and 4 only                 

    D) 2, 3 and 4

    Correct Answer: A

    Solution :

    The given reaction can takes place only by \[{{S}_{N}}1\] hence statement 1, 2, 3 and 5 are correct.
