    The following reaction is described as

    A)  \[{{S}_{E}}2\]         

    B)  \[{{S}_{N}}2\]

    C)  \[{{S}_{N}}1\]         

    D)  \[{{S}_{E}}1\]

    Correct Answer: B

    Solution :

      In the above reaction inversion takes place hence, it is an example of\[{{S}_{N2}}\]reaction. In this mechanism the attack of\[O{{H}^{-}}\]ions take place from the back side while the\[B{{r}^{-}}\]ion leaves from the front side.
