Question
In the reaction given below,

which of the following statements is correct
A.
The reaction proceeds $$via\,{S_N}2$$ mechanism hence inversion of configuration takes place.
B.
The reaction proceeds $$via\,{S_N}1$$ mechanism hence inversion of configuration takes place.
C.
The reaction proceeds $$via\,{S_N}2$$ mechanism hence their is no change in the configuration.
D.
The reaction proceeds $$via\,{S_N}1$$ mechanism hence there is no change in the configuration.
Answer :
The reaction proceeds $$via\,{S_N}2$$ mechanism hence inversion of configuration takes place.
Solution :
Inversion of configuration takes place in $${S_N}2$$ mechanism.
