The following reaction is described as
A) \[{{S}_{E}}2\]
B) \[{{S}_{N}}2\]
C) \[{{S}_{N}}1\]
D) \[{{S}_{N}}0\]
Correct Answer:
B
Solution :
In this reaction inversion takes place. Hence, it is an example of\[{{S}_{N}}2\]reaction. In this mechanism, the attack of\[O{{H}^{-}}\]ion takes place from the back side while, the\[B{{r}^{-}}\]ion leaves from the front side.
