Question: In an SN2 reaction, what is the stereochemical outcome when the nucleophile attacks a chiral center?

Options:

Correct Answer: Inversion of configuration

Solution:

In an SN2 reaction, the nucleophile attacks from the opposite side of the leaving group, resulting in inversion of configuration.

In an SN2 reaction, what is the stereochemical outcome when the nucleophile attacks a chiral center?

Step 1: Identify the chiral center in the molecule where the reaction will occur.
Step 2: Recognize that in an SN2 reaction, a nucleophile (a molecule that donates electrons) will attack the chiral center.
Step 3: Understand that the nucleophile approaches the chiral center from the side opposite to where the leaving group is located.
Step 4: Visualize that this attack causes the configuration of the chiral center to flip, which is called inversion.
Step 5: Conclude that the final product will have the opposite stereochemistry compared to the starting material.

SN2 Reaction Mechanism – An SN2 reaction involves a nucleophile attacking a substrate at the same time as a leaving group departs, leading to a single transition state.
Inversion of Configuration – The stereochemical outcome of an SN2 reaction is characterized by the inversion of configuration at the chiral center due to the backside attack of the nucleophile.
