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 :

Sol.         In the above reaction inversion takes place hence, it is an example of\[{{S}_{N}}2\]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.
