Question

What is the stereochemistry of the product(s) for an $S_{N}2$ Reaction?

• A. $R$
• B. $S$
• C. Racemic mixture
• D. No chiral center in the product

Answer 1

The correct option is D No chiral center in the product

The reaction between pyrrolidine and $1$-chloropentane gives $1$-pentylpyrrolidine.

It is $S_{N}2$ reaction (bimolecular nucleophilic substitution reaction) in which chloride ion is replaced with $N$ of pyrrolidine.

$S_{N}2$ reactions involve inversion of configuration. But in this example there is no chiral center in the product.

Option D is correct.
