Question

The reaction below is an example of an intramolecular $S_{N}2$ substitution. The stereochemistry of the product is :

• A. meso form
• B. pair of enantiomers
• C. pair of diastereomers
• D. only one enantiomer

Answer 1

The correct option is D only one enantiomer

Since the reactant is chiral and optically active therefore only

one enantiomers is formed by intramolecular $S_{N}2$ reaction.
