An SN2 reaction at an asymmetric carbon of a compound always gives

N S 2 reaction is the nucleophilic substitution bi- molecular reaction in which the leaving group is substituted by a nucleophile. This is a bi-molecular reaction which means that in this reaction, the slowest step involves two molecules. Let us see the mechanism of N S 2 reaction. As we can see that a transition state is formed where both the leaving group and the nucleophile is involved. Now, in this transition state, we can see that the nucleophile is attached from the opposite direction to the leaving group. This means that there will be an inversion of configuration which we can see in th
